A solid concept, and at first it was kind of fun. But be ye warned going in, any who download this game: If you are not a fan of rage games (that is, games that are deliberately hard by virtue of being unintuitive and clunky, often frustrating the player as a result) then you will not like this one. The physics based movement is a fun idea, but to me it felt floaty and inconsistent, like the momentum tapered off far before it should have, making seemingly easily doable jumps into a nightmare of coming up short or flying way too far. Your momentum carrying over from one life to the next is also a source of frustration for me, as it led to at least one time where all three of my lives got blown away all at once because my residual momentum from life 1 led my square to fall into a death pit right in front of spawn.
There is also a game-breaking bug that occurs sometimes where, for whatever reason, the game doesn't register the square as being in contact with a surface, making it impossible to move until the timer runs out and kills you.
Credit where it is due, the yellow cube at the start adds a layer of whimsy that helps soothe the ache.
If you're a player who is more inclined to enjoy rage games, like 'the world's hardest game' or literally anything Bennet Foddy has ever produced, you'll be right at home here. Otherwise, it's probably best to abstain from this one.
Unless you are just morbidly curious. In which case, play away.
