In a world where magic and technology intersect, the tale begins with a young stray cat named Shadow Cat. Unbeknownst to him, his destiny unfolds when he encounters Clock Wise Cat, a revered professor who sees the untapped potential within him. Shadow Cat is welcomed into Clock Wise Cat's academy, a clandestine institution of knowledge and magic hidden from the eyes of the ordinary world.

Despite his prowess, Shadow Cat finds himself isolated from his peers due to his immense power, which instills fear among the other cats. A loner by nature, Shadow Cat delves deep into the ancient tomes of Clock Wise Cat's library where he stumbles upon a book about the Omega-Verse.
Intrigued, Shadow Cat started to learn more about the Omega-Verse theory, a concept believed by ancient wizards that suggests an infinite number of universes exist within the Omega-Verse, each containing alternate versions of oneself.
Fascinated by the concept of parallel universes inhabited by alternate versions of himself, Shadow Cat became consumed by his studies. His ultimate ambition: to unlock the secrets of the Omega-Verse and reunite with other iterations of himself, whom he deems as his true family.
Through relentless dedication, Shadow Cat starts to experience visions of other worlds and establishes communication with fellow Shadow Cats across the Omega-Verse. They forge bonds and pledge to unite, vowing to conquer the Omega-Verse together.

Years pass, and Shadow Cat ascends into adulthood, assuming leadership of a faction known as the Cats In Black. Harnessing his magical prowess and understanding of the Omega-Verse, Shadow Cat collaborated with Top Hat Rat Technology to construct a network of quantum computers, enabling interdimensional transit.
The completion of the device heralds a new era of exploration, as Shadow Cat pioneers communication between universes via this technology. However, despite advancements, attempts to transport organic life result in catastrophic failure, with subjects succumbing to fatal tumors upon arrival.
Meanwhile, Top Hat Rat, overseeing Omega-Verse operations, harbors ambitions of traversing dimensions for resource extraction, driven by scarcity in his own universe.

After countless trials, a breakthrough emerged when a single mouse defied the odds, surviving the interdimensional journey. Dubbed "Omega Mouse," it became the focal point of reseach and experimentation by the Cats In Black throughout the Omega-Verse.
Amidst the frenzy of their endeavors, Shadow Cat had a stunning revelation. It became clear to him that within the vast expanse of the Omega-Verse, where infinite possibilities lay, there must be a universe where Omega Mouse is more powerful than him - a universe where Omega Mouse reached it's prime.
With it's inherent power of interdimensional travel, Shadow Cat knows it's only a matter of time before Omega Mouse Prime shows up seeking retribution against him and his allies for their many crimes against mice across the Omega-Verse.

Omega Mouse Zero seems alright and full of potential honestly, It's got some pretty strange vibes, I was starting to get into it. ..but then I encountered a bug where I wasn't able to save at a save point, despite it having let me do it at the past few I had encountered. I eventually died somewhere with plenty of progress lost and lacked the motivation to redo everything. Maybe if that bug can get fixed up I will revisit this one day.3 found this helpful
This could have been a decent small indie game, but the meaningless map and poor shooting ruin it. UPDATE: Changing to recommended. Recent patches and updates improved the map; now it changes and removes icons as you collect items. The story involves an evil organization seeking to govern all dimensions. Only in one dimension was Omega Mouse able to vanquish the organization. Now his goal is to release all other identical mice in other dimensions and form an army capable of defeating the organization. That's why the game begins with a hero who has already completed all upgrades, equip, and missions. However, this is only available until you rescue a new mouse, who will become the next hero. You just get a gun and a shield and lose everything else. The goal is to explore the facility and recover all equipment. You have a variety of combat abilities at your disposal. There's a basic gun, kick and roll, a far more useful shield that stops most projectiles, a secondary fire that fires additional projectiles, a missile launcher, and a force field. Everything will need to be found first. The missile launcher has limited use because of limited ammo. The same applies for the force fi…3 found this helpful
Metroidvanias with hard rock music have a history of being very bad. Metroidvanias with anthropomorphic mice also have history of being very bad. This has both. My hope is that two very negative trends would cancel each other out to produce a good game. Unfortunately that didn't happen but it was not for the reasons I expected. It turns out the reasons this is bad are as follows: - The map is completely useless - The game decided to try out a unique 2.75D style. How should I explain this... do you remember those old arcade beat em ups how you had to move into lanes and could only attack baddies in the lane that you are in? well, this game has that, its the first metroidvania ever made to feature that. Unfortunately, it doesn't work out at all in practice. The reason why is that it is usually very hard to see which lane the enemies are in, enemies can shoot at you from any lane but you can only attack them on their lane. It's too bad this doesn't work really, this could have been a really fun originaly metroid like - The performance is too poor when there are too many entities nearby, which is weird because my CPU was recently adjusted to be able to handle lots of stuff thrown at…2 found this helpful
Omega Mouse Zero has a lot of redeeming qualities the only issues i had were the controls. Trying to do a midair kick is hard when you are using WASD controls. BUT that does not mean i did not enjoy the game! It has the feeling of a good metroidvania it's just some of the controls feel wonky. 8/101 found this helpful
The game itself has potential, but the 2.5D is badly designed and makes what should be a fun game intensely frustrating. After getting stuck in the same area for about 45 mins, because it is hard to establish depth perception wise, were to shoot from, especially when the enemies are above you, I gave in and I will not be returning to this game unless it is fixed. I love a challenge and honestly would have given up sooner if I wasn't so stubborn, but having played some other 2.5D games in my life, this isn't a challenge; it is just badly executed.1 found this helpful
