It's a very pretty and polished game, but I struggled a lot with the controls. I tried to read most of the text at the bottom but because it flashed on and off I had trouble. My biggest problem was that you can't dash when you have an arrow key pressed, and that took me a long time to figure out. It was quite difficult to see everything as well, but I managed.
The sound is awesome! and the level design is well done (but I think it was difficult to tell what the level design was because of all the stuff on the screen). Max 2 more colors would have been really cool, and made it much more readable. I made it about halfway or more through the game before I realized the evil essence killed the skulls. My biggest problem with the enemies were the tiny little circles that moved straight across the screen and killed instantly, because they were almost impossible to see.
If you can make this in 48 hours, you could make something really amazing in even longer.
