Evolution Shmup is Petri's experimental attempt at creating the perfect vertical shooter by tracking the amount of time that a player spends on each random iteration of a new game. Every refresh creates a different result, using elements from versions of Evolution Shmup which players have spent the most time on.

[This game is one of the entries into TIGSource's Procedural Generation contest.]
