Hi! The way we thought it was that the river and the canals are connected, so you try to keep the river at bay by unclogging the canals, and originally the game shared mechanics with an infinite-runner. Still, we have to workshop it a bit after the jam. And about the controls, we wanted to give the player some challenge in the main mechanic so that they had to put some effort to aim, so thanks for noticing, and thanks for the feedback!
