Now this game was SOMETHING. Great job on the theme interpretation idea - playing on a rubik's cube and spinning the enemies and spawners around was really fun and fresh!
I also found the top view really useful to see where the spawners and crystals were. I also liked that the art changed the more powerful you got. Great job!
If you want to improve on this further here is a suggestion - I had to look away to the bottom right of the screen to see the status of my dash and slams - keeping those indicators close to the player would let me know their status without having to look away from the action. Maybe they wouldn't need to be hud elements at all - a little sound or some smoke or something could do the trick.
This is just a nitpick tho, kudos to you on making this. I had a lot of fun with this. You should be proud!
