Good entry! The graphics and music are nice and the game feels good to play.
Some people talked about a bit of lag about leveling up, I didn't feel that lag. However, I felt a bit of lag during gameplay, I think the massive amount of enemies was the cause of this. Now I don't know if I was playing it wrong or my computer is a toaster lol
Other than that, I think you guys did an amazing work, it is really well made! :D
