I don't really like it. The concept is nice, I upgrade system is ok, but I get hit becouse of -MY- bullets. theres so much flickering green on the screen, it makes my eyes hurt an the enemy bullets hard to see. Bonus lvl is quite easy once you upgrade wave & chargespeed.
Great game. Loved the ending and the writings. The number to start with was not to hard to figure out I think, and except for bone + stone the puzzles seemed quite logical to me.
Walkthrough:
Max out young man (ignore the few that pass thru), then save Money for Glutton, max him out, save for Glutton, max out and so on. beat the game with that.
