If eventually you wanna give it another try, on the level selection you can just skip one if you get stuck. (ideally the following levels are more difficult but I struggled a bit to define the difficulty).
Happy that you liked the music! I'm not the author, I wish! The author is Isaac Ebert( https://www.gamedevmarket.net/asset/8-bit-chiptune-puzzle-pack-2 )
Thanks for the honesty about the dash command! Initially I considered to just be always dashing by default, to avoid the extra key. But it was too chaotic and I choose to make it with the Z + direction. And even if myself I had to check the keyboard and it didn't feel too natural I thought "It's turn based, it should be fine". But it seems it wasn't hahaha
Super thanks for spending the time on the game and this proper feedback! I will try to do the same I when I play yours!
