Hello ! I kinda agree with AxalKay, even if I couldn't finish the game. It gets hard really fast ! And I was blocked at level 1-8 (maybe I'm dumb however). The feeling is great tho !
Thank you for giving it a shot! I will also look into level 1-8, though I think it’s just a much harder puzzle than anything in the game thus far, which is something to address for sure.
