I like this. Relaxing. And satisfying when you solve a level. Good difficulty curve as you progress. I will note one very minor frustration. Parts of Level 20 are just traversing to the next puzzle room. Having to move one square at a time just to cover that distance after a death/reset is every so slightly annoying. I can't think of anything else I didn't like, though. The first three levels, I would say, are the tutorial. Level 4 is the first real puzzle (and it's appropriately gentle). But I remember playing the first three levels and thinking this game is too easy. Why am I getting three stars for doing essentially nothing? Maybe making it a little more obvious that the game is just teaching you in those first few levels would prevent cynical bastards like me from smirking. But then again, there's a lot to be said for showing rather than telling... Very nicely done overall.
Hey thanks so much for your feedback—glad the difficulty curve felt good.
Yeah, I see what you mean. The check points are always placed as separate rooms between puzzles rooms to kind of break the rhythm and function as architectural interest. But I see your point. Will see if I get more feedback on this from others.
That gives me an idea, regarding the tutorial levels. Maybe if I overlaid some arrows and stuff, it would feel more like a tutorial so first-time players won't think the game is too easy.
