About Project R.A.T.

✦ AI summary

Project R.A.T. puts you in control of a mutated super-rodent launching through a hazardous laboratory in gelatinous form, slinging and slurping your way toward freedom. This atmospheric single-player adventure stands out with its creative premise and physics-based movement mechanics that make escaping the lab feel as bizarre and fun as its concept.

Take control of Chris P. Ratt, previously a diabetic test subject, who has now been mutated by an exceedingly high dose of cannabidiol into a fully capable super-rodent!

Sling, slip, and slurp your way out of the dankest of labs to sweet freedom!

Key Features:

  • Launch across the lab in your gelatinous form
  • Avoid hazardous materials to survive
  • Make your way through an atmospheric single player experience
  • Student Created Game

✦ AI summary

Project R.A.T. is a short puzzle-platformer with an interesting core mechanic centered around goop-based movement that shows creative promise, but most players agree it feels unpolished and incomplete, more like an early prototype than a finished game. While some players enthusiastically praise the clever level design and unique parkour elements, the common complaints focus on its brevity, control issues, and overall lack of polish.

"Project R.A.T." seems more like a tech demo or student project than a fully developed game. It's quite short, unpolished, a few bugs... it could use a bit better control definition, too. The idea of this game is you control a lab experiment rat and go through some puzzle platformer levels (but not many). This is one of those games that shows promise but needed a lot more work. The graphics in this game are passable, but could be better. And while it's vital for any game to have impressive visuals (gaming is a visual medium, after all), there's more to a game than just the graphics. To be worth a gamers time, the game must match top tier visuals with top tier gameplay, and that's not happening here. Not every "free" game really is. There's often MTX, or content locked behind DLC, or donations being requested, or any other number of things that could mislead gamers, but in this case I'm glad to say this really does appear to be a fully free game. Nothing demonstrates a developers belief in themselves and their work than giving it away without any remuneration. This is a service to themselves, and the gaming industry, and should be applauded. Of course, just because someth…

I love this game so much, so today i am going yo right a 5 paragraph essay explaining why this is the best puzzle game, best parkour game, and the most speedrunable game. I hope you enjoy This is the best puzzle game ever. The green goop parkour is just so smart and thought out (I wouldnt have thought of it in years) and the buttons... very smart and thought out (i wouldnt have thought of it in years) its just such a smart game, i would have never thought of these levels or anything its just like a 39345894083 iq creator, how is this game not #1 on charts? No grammy awards? Yeah its a game, its just so good it could be a film, why isnt it a film???? This is the best parkour game. Nobody likes jumping, oh wait... YOU CANT IN THIS GAME. That makes it 10x better than the average parkour/platforming game on this platform. You must go from goop to goop instead of stupid platform to platform. (no jumping) that is good. So is this games graphics, they are the highest quality on this platform, forza 5 looks like pong to this game. It is so good. No lag so parkour is easy, did i mention you dont have to have a good pc? YOU COULD PLAY ON YOUR PHONE. This is the best speedruning game. This…

Project R.A.T. — увлекательная инди-игра с атмосферной графикой и оригинальным сюжетом. Геймплей сочетает элементы экшена и головоломок, требующих стратегического мышления. Отличная реализация механик, динамичные бои и глубокая вселенная с множеством скрытых деталей. Однако сложность некоторых уровней и недостаток подсказок могут отпугнуть новичков. Рекомендую тем, кто ценит креативные проекты с непредсказуемым сюжетом.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
