Get chased by exclamators. Collect candies to get bombs. Blow up exclamators. Repeat

Ideas for later:

Smokescreen pickup: Exclamators cannot detect player. Will wander randomly for 5-10 steps

Gold candy: Special candy which gives quadruple points. Is invisible, flashes every 5 steps, relocates if not found fast enough

Hats.

Enemies spawn in larger numbers as the game goes on

Enemies move faster as the game goes on

Randomzied walls in the middle of the arena

Arena walls may be boobytrapped. Running alongside a wall may result in death/stun to disincentivize this tactic

Save game scores in db

Exclamators should not be able to fall into the same tile

Hats.
