It's alright, it could use some music. The biggest issue I've found is that there seems to be a bug with prestige. I believe the point of prestige is to remain at whatever rank it was when you reset, thus giving you the bonus to reach a higher level. What actually happens is, you will get that rank initially, however once you start spending your experience, your prestige rank drops along with the multiplier.
If this is intended, I don't believe it should be as it makes resets only useful for buying prestige bonuses with experience, but makes it take forever to gather experience again.
