Addicting!
For such a simple concept it's pretty fun. It seems easy enough, punch docs, get drugs, but I love the challenge when you take a hit and you don't know what to expect with the game-play. I think you could make the doctors easier to start off with and then get progressively more challenging so you don't have to restart so often. The music is great and does go with the psychedelic feel, but does get old after awhile; maybe change it after several rounds. All in all, for such a straightforward game, it's very entertaining. Nice work!
