5/10
Because its has ALOT of glitches.
For example:
After lvl 6 (the boss battle there was to press left arrow and space.I did that and i lost.But i got over to "Stage cleared" (Lolwut?) So i clicked "Continue" and it got me back to "Stage cleared!". So i clicked it again.And again.And about 10 more times and i got now 52k gold.AND I CANT PLAY!It got me back again to "Stage cleared!"!!!! -.-
