Drop twikoi's creatures into the jar. Two of the same squish together into the next creature. How far up the chain can you go?
Slide left and right above the jar to aim, let go to drop (or arrow keys + Space).
Two of the same creature touch and squish into the next creature in the chain.
The chain lights up as you reach each creature. Every jar has a new chain!
Merges that set off more merges are a chain: ×2, ×3... points.
Keep creatures under the dashed line. If one rests above it too long, the jar is full.
