Basically, these are SOME of the moves that players can perform in the game by using 'z', 'x', 'c' along with 'up, down, left, right'. Players can try different combos like 'c' and 'x' to have a cool attack move.
The fact that this game also use a puzzle-like element make it a fun and good brain exercise too. I also like it that players can go into any level they want to hahaha. To me, its idea of 'joining single attack with other moves' does incorporate with the theme of 'Joined Together'.
My suggestions would be: to decrease cool down time after performing an attack like the slash coz it'll be more thrilling and easier to manoeuvre the character away from the impending attack. Another one would be, music and killer sound effect coz developer art style is already satisfying, unless they want to add a little of this and that. Oh, also maybe add the 'z,x,' into the tutorial because I was having a brain leak for a few minutes trying to figure out how to attack as I know there are 'combos' element coz I read other comments.
Overall, Good Job DamenMaughan :)
