Nice game, the encounters start really easy then get super hard. You can stick to the left side for the salmon run. At the start it seems way too easy, I'd def put a count down timer of how much time is left I almost thought I was supposed to die or something.
I think you could tune the encounters to be much shorter (and get into and out of them much faster) by making them last far less time but only giving you 1 hit instead of three.
I'd scale back the difficulty on the later encounters. The twin guns are hard I don't think I ever passed it, I got past salmon twice out of 4-5 attempts. I got the shooting start once out of 3 times, I didn't get past the candy swirls. The frog and the flies are way too easy however.
Nice game, thanks for playing mine.
