I love it! Mechanics are quite interesting, both the movement and the tide thing. Animations are cute.
Unfortunately, I wasn't able to proceed to level 2 cuz game just freezes in the end of the first level, no matter what I'm doing (I tried about 5 times). Sound and music are great, but the jump sound is too loud.
Overall I'll definitely play this game more once it's finished, I'm looking forward to it!
