It's just okay. Not very good, not very bad.
This is a great retro game :) I love it! ^.^
Old school greatness. <3
Great sfx and mechanics, a really fun game, somewhat addicting.
i actually think that this game is really great. the upgrade mechanics could use some tweaking, but what i think made the game worth 4.5 stars was the beutiful retro graphics and its great soundtrack and level sounds.
