I loved this game! It wasn't that difficult of a metroivania game, but short and sweet. I loved that I could get lost and explore. Some of the collectibles are missable, but that's fine, as they are only there to boost the score. What really sets this game apart from other pico-8 games is its presentation. From the little exes at the end of each speechbox, to its well designed water physics, it akes it seems very professional. One thing I would add is something at the beginning to show you the controls, as even though this would be great on say, an nes, many beginners won't know which button is which on keyboard. Also, you could try adding a map, but then the game would be too easy for more experienced players.
The game took about 15 minutes, and overall was a solid experience, 5/5
