I liked the character design and animation. The attack animation looks and feels good, but I had a little trouble with the timing as it's not entirely clear at what point the sword hits the projectile/program. I would have liked the tolerance range to be slightly wider here, since I had to repeat the tutorial several times.

the tutorial is a bit too long, if you die during it you have to start the whole thing over. the game is quite hard but it looks great

It plays well!
Maybe there are few timing issues when i hit the green programs. (or skill issues) .
Just a thought, but maybe you could mention again somewhere that you select menu items with "Z."
