I finished your game, and it took me almost 15 minutes and 500 flops!
Needless to say- the gameplay was engaging. I was on a verge of ragequit a couple of times. The game felt challenging, but fair, so I kept trying. Every time, it was obvious what I was doing wrong, so it was never about figuring out what the game wanted from me.
For this reason I think your game does the theme especially well. Yeah, like many games it's about something returning home, but because your game was pretty challenging it sold the LONG of "long way home" better than the most.
Minor nitpick- the jump arc was a bit shorter than the actual jump. I got used to it, but it was a bit misleading at first.
The graphics and sound were ok. The slurping sound when the fish landed in water was pretty funny. At some point there was a strange sound in a background (like a saw?).
Over all- VERY enjoyable gameplay! Keep at it!
