The game itself is way too easy. With or without pills - no difference. The first time I started the game, I never lost; I Won 4 times in a row instantly, two times without pills and two times with.
The idea of the game is excellent, but we need some hard mode and AI improvements in single-player mode.
+ I would love to see two extra modes:
1. online multiplayer
and
2. local online 1vs1 mode, aka Hot Seat
Game Design 10/10
Audio 9/10 (more songs would be nice)
In-game content 6/10 (local hot seat + online needed)
Difficulty level 2/10
Overall: 8/10, great job
