Fun little game, the Gura art is really cute, and the controls work pretty well.
I think I cleared everything up, with 0% remaining and not holding any slime, but there was no pop up or anything, so I'm not sure if the completion state is working.
An idea I had was having the enemy fish respawn after a set amount of time, since once you defeat them, they're just gone forever, and while they don't really seem to pose a threat right now anyways, it would still give some challenge to avoid them and keep up the combo. Also some combo incentives would be interesting to see, I can't tell if there's any bonuses for a building combo in this version.
Regardless, thanks for sharing with us, good work to the team, and hope you all can keep expanding it after the jam!
