Hey man, I did my full 10-minute review during my Twitch Stream Friday night (twitch.tv/aaknox), but I'm going to summarize what I said during my review:
Art: Everything looks very vivid and precise. Colors look great.
Animations and Controls: The particle effects were very crisp. However, my biggest issue was with the controls. The camera control with the mouse is only a good idea if the movement of the player is also controlled with the mouse. The separated controls only make it very difficult for players to see where they are going. I strongly suggest that you make the camera fixed to one point on screen or (if you still want the follow effect) just have the camera attached to the player in some way.
Sounds and Music: The sounds are very well done.
Overall gameplay: The way you worked the game into the theme is very well done. However, I think you may need to balance out the dash vs. jump upgrades a little better. After 2 jump upgrades, I jumps over 10,000 into the air; after 2 dash upgrades, I am still unable to clear a 100-foot gap between platforms. Other than that and the controls, the game is a well-done speedrunner.
Hope this review helps your team grow!
