Very nice game! It could definitely use some tuning, but it is fun!
I like that the pot stays in place while it attacks, like if it was burying its roots and emerging elsewhere. It makes for a good challenge. The art is cute.
I feel like the camera lags too much behind the pot. Since it moves so quickly, it's almost impossible to see if you're going to hit something and when you should stop.
The whole scene could be a bit more zoomed out, and it'd be nice to have some pointers in the directions the snails are in the map so you're not wandering for too long while searching.
You get so much money in the first rounds that you can almost always buy every upgrade, so maybe turn it down a little xD
