I like the game, but I found myself constantly spamming the spacebar. A suggestion would be to have the player continue to dash while spacebar is held. While playing I thought for a while there would be a big fish the deeper I went, that would be a fun challenge if say you had to maneuver through small passages to escape obstacles like that.

The dash is kinda hard to use, but I love the idea of kinda open world 2d game.
