LAMBDA end THEORY is a short, mysterious game. And honestly I don't really want to say much more about it lest I give anything away. Playing through it kind of reminded me of playing through Cave Story way back when. Though mechanically very different both games throw you into things without any explanation or tutorials or even mention of the controls. Your dropped into this world with no idea who you are, where you are, or really idea at all, and it's only over the course of the game that you piece these things together. The music, as i'm sure you heard from the trailer, is also very good and helps set the tone for everything very well. There's so much more I want to say, but given how short the game is I think it's better for you to simply play through it yourself. That being said there are a few things I feel I should mention. Most notably is the combat. To "charge" your "attack" (neither of these things are really explained in detail) you have to rapidly mash a button, either the enter key or A button on a gamepad, so if your somebody who struggles with button mashing that may be something to take note of. From my playthrough the button mashing always seemed to be at a managea…

Nice and short pseudo-RPG. Four worlds consisting of around ten screens each, with most screens having either enemies, NPCs or basic puzzles. Combat happens automatically and can be influenced by mashing a button, which is not good for accessibility and ends up hurting your wrist without bringing too much to the gameplay ; fortunately, you don't have to mash as fast as you can and there aren't too many of these battles. I wasn't fan of the system, although finding power upgrades and getting stronger always felt nice. Exploration is done by walking to places and interacting with either NPCs or items in order to get a power up and a key for each zone, before fighting a boss. The puzzles that lead you to these items are good! They're very "simple" in that they can even be "wait five seconds here", but they can be a bit tricky and there's a good Steam guide to help with them. And that's about it! [b]LAMBDA end THEORY[/b] is less than an hour long, looks nice, doesn't have much to say, but makes up for it with a cryptic and interesting atmosphere. Pixleaves also developed a prequel for the game called Me && MORY which might give the background a bit more heft. I recommend giving the …

This is a cryptic puzzle adventure game with a minimalist 8bit style and light RPG systems. I think it succeed on what it aims to achieve as it’s very focused on that goal, so if you’re in that specific type of experience (a very cryptic one) you should not be disappointed. The chiptune music in particular is very good, it participates along with the visuals to bring life to this intriguing “digital world”.

LAMBDA end THEORY is very cryptic and it does it well. The game is quite charming with its retro-ish graphics and music style. You will feel right at home if you have been playing games on the Game Boy console (which this game seems to be paying an homage to). I also like the fact that the overall universe and ambiance are shaped around IT, such as programing terms, data, binaries, etc. Enjoy! < Review > - The story is intriguing and mysterious as expected with some interesting twists! - The gameplay itself is straightforward, but easy to learn. - Battles are simple and automated, but you can do some critical hits by charging your attack while smashing the corresponding button. This does give them more life and involvement from the player. - The musics are very charming and definitely give a nice throwback to the Game Boy era. - The pillars / dungeons have their own theme with some references on IT stuffs. < Suggestions > - The battle system has some issues with its interface. I have troubles to stay focus on the battle interface and the characters while fighting. I think it would be nice to change the battle interface to have the Life Points displayed as a gauge on correspondin…

Although I can't say I'd recommend Lambda end Theory, it definitely has some cool elements! This game is definitely as advertised: very mysterious and cryptic. It's got a super unique atmosphere, and the world building is intriguing. The puzzles are very hit-and-miss though, some being pretty fun, based logic or word-association, whereas others are monotonous, or hampered by confusing wording (in the English version at least). The combat system also adds to the monotony. It's turn-based, but you have to mash the A button to deal more damage. It gets old pretty quick, would have been nice if it was either faster so it didn't overstay its welcome, or had some tactical/puzzle elements to make it more interesting. It also didn't help that enemies respawn as soon as you leave their room, so there are a lot of repeat battles that make figuring puzzles out a lot slower. To players: if you're interested in giving it a try anyway to experience the atmosphere and world building, I'd recommend looking up a walkthrough if you get stuck! That'll make you have a much better time. To the developer: I encourage you to keep trying to make cool atmospheric games like this! The environments, musi…
