i already tried this game, and this is AWESOME!
and i want to write my impression:
what i like is
1. this game has sound effect and music
and i'm a bit surprised you choose a fight music XD
2. sound effect is good, not make me feel dizzy :D
and when i choose the wrong combo, game automatically reject the combo, so it will minimize the error
3. and ussualy, i don't really like Unity game because it's slow on my computer (yes, my leptop is potato XD)
but this game works fine, and i like it!
4. i laugh because Nani sfx XD
and my feedback is:
1. add main menu!
2. add tutorial inside game. because it's will make the game easy to understand
3. add Credits too! so people know who make it :D
4. and add fullscreen option
other than that, this game is really good. i never think this idea before and i'm glad someone make this game
thank you and keep creating!
