Shooting for Substitution APK

Only collision with nucleophile renders reactive compound invisible.

This is a game about nucleophilic substitution. In DMSO solvent, you shoot (fling with your finger) a nucleophile rocket (-SCH3) at various compounds zipping around randomly. Some compounds are reactive to your nucleophile and some are inert. If you knock out all the reactive compounds (perform all the substitution reactions), you win. However, if you hit an inert compound, you lose a life. If you are down to 0 lives, you lose. But you can always hit "REPLAY".
