Ideas are simples but scale ;) in complexity very quick
I would enjoy a skip button to get an overall look

I do like grid-based games.

Interesting mechanics! It's seems basic at first, but it is actually used in some clever way!

However, the game is really tough to beat. Like, in a way it sure make the puzzle interesting. But boy did it take me a lot of time to reach the end! The game doesn't really give you time to learn some of the complex technics, it's immediately really complex. Combined with the finnicky physics that makes you doubt if you're actually allowed to do some of the moves, it makes finding te solution tedious. On the second half of the game, although I felt clever for finding some part of the solution, I also wondered if I wasn't cheating by using some kind of speedrun hack. Although there are some good ideas, the fact that levels takes so long to be resolved makes it less satisfying to find the solution.

Also I do like that they are secrets level, and how they are introduced! That's actually the kind of enigma that is really satisfying to resolve.^^ My brain was already melted though, I didn't complete the first one. :p

Still congrats for making not only a puzzle game, but actually a difficult one with clever surprises! I'm pretty sure a better learning and difficulty curve (and also a more precise physics) could make it work really well!

Love the math style, kinda reminds me of older flash games so this is cool

This actually have a lot of stlye and creativity, the mechanics are quite amazing and unique, but the lack of consistency to solve the puzzles make it really painfull, its not more about solving a mistery, but forcing the game to achieve a victory mearly casual
