Interesting spin on the flappy bird style of game! It took me a while to get used to how the fish bounces up and down and goes off the wall but I eventually got the hang of it. The core of the gameplay is well done and it looks nice. If I have one criticism it would be that the difficulty curve could use some work, for example it might be better to have fewer streams of fish early on, and more spaced apart or slower and then do a gradual build-up to more fish that are faster. All in all though it was a pretty fun little game!
