Great game dude! I love the mechnic and how you progress through levels with the converyor belt. A few things though:
1. Use a different font than arial. You can find good fonts on sites like Google Fonts.
2. Make it so that the music loops.
Other than that, great game. I'll definetly finish it later. I hope the feedback helped you, and it would be nice if you could check out my submission too. Thanks. :)
