Initially made in 48 hours for #ConstraintsJam but I got the deadline confused.
This game has the following three constraints:
1. Game must have 30 second levels.
2. Game must use 3 colors or less.
3. Game must have single key control scheme.
Update: Oh wait, the deadline has been changed! I guess I made it after all.
