I don't know if it's too difficult or is it a skill issue, but for now i got 11 in level 2 and i'm stuck. I'll keep playing cause i wanna see further levels but so far, i would really love to be able to move with WASD also, like enabling both arrows and WASD would be perfect. Also the sounds are great but i hope the music was a bit more quiet and maybe more peaceful, would make a better fit. But thats just my opinion dunno haha
