A really fun game with an extremely well-designed and fluid movement system. The soundtrack is awesome too, and I'm really glad you included a tutorial to help new players understand the game better!
My only criticisms are that there isn't enough feedback for certain actions, e.g. damage taken, sliding, enemy killed, plus there were multiple instances of enemies following me right behind my back, so I had to purposefully take damage in order to gain enough momentum for an escape, so I guess I would've preferred enemies to emit a subtle audio queue based on how close they are to the player (similar to what Devil's Daggers did)
The dash mechanic was the only thing that I didn't actively enjoy. It felt too stiff, and again, there was not enough visual feedback. Blinking forward a short distance just didn't feel satisfying at all
Also a minor thing, but the cooldowns of abilities are a little hard to spot, the background blends with them a bit too hard
Do keep in mind that these are just my opinions and don't take them to heart! That's still an awesome game, and it's honestly insane that you guys pulled off this project in just 7 days!! :)
