This was a great game! I loved all the obstacles, and the addition of a whale chasing you if you get caught in one was a really nice touch. The art is beautiful, and the krill is especially cute. I also really liked the little swimming animation and the streaming water effect around the krill.
I did find the game a bit easy, and it got a little repetitive after a while (though maybe that’s normal for an endless runner). Since I couldn’t pause the game, I had to pull out my phone to record my thoughts so I could remember them. I suppose the fact that I was able to play the game, pull out my phone, open the recording app, and continue playing at the same time is a testament to its easiness (or maybe I’m just too good at multitasking).
I have a few suggestions that might make it even more engaging. I agree with one of the previous comments about the point system, and I’d add: the music is a bit repetitive, and the rate at which the runner speeds up feels too slow. It might be fun if the music became more intense as your score increased. Most obstacles spawn near the top or bottom, so staying in the middle makes dodging too easy. The whale was super cool! I think it could be interesting if it appeared randomly, and maybe that could cause the speed of the runner to temporarily increase so it creates a greater sense of urgency and danger. Adding a boost/dash or some kind of collectible power-up could also make gameplay more exciting.
Overall, this game was very polished, fun, and cute. Great job on your entry!
