Got some performance issue while playing the game not too sure why maybe some code logic error which causes infinite loop or something that you need to check out for. I liked how you designed the logo so that the it actually fits perfectly. Some feedbacks:
- Not too sure why do I need to collect things like the shells except for the power since there are no scoring system in the game. Probably you can make it like an achievement kinda things so players can actually have the motive to collect things.
- The power draining seems a bit too fast for me (prob im just a noob ;p) but it would be great if it resets whenever enter a new level.
Overall, good entry!
