Decent enough game, though I started suffering some major lag within the later levels and I didn't have any other tabs open, nor was I downloading anything in the background. You may wish to look into that. Aside from that minor issue the game was servicable, albeit short. Decent enough effort.
What are the secret medals??? D:
Got stuck on level 7 i kept on diying!!
Need some improvements and there are some glitches as you can probably see, but this is great for 72 hours! I love the music. I really hope you continue to work on this and improve it till it's a masterpiece. It does feel a little repetitive, and try not to make the levels too challenging.
I agree with everything EpicXInfected said. Just feels like it was made in 72 hrs
