Despite the respawn issues (it seems the game forgot I had gotten the artifact, because the rocks on the way back from the final room stopped shooting at me, but I somehow still got the ending screen when making it back to the start?) , I had a lot of fun figuring out each room. Felt a bit empty at first, but from the second area it picks up the pace. The way each biome has a very different visual mood makes the journey exciting, lots of pretty environment elements. The music's good, but a few of the loops felt a bit too short/repetitive. I would have favored a bit more lenient hit detection with the spikes, sometimes I didn't feel like I was getting hit, but hit I did get. It's a bit hard to get around while swimming. The HUD makes it look like you could get more hearts, but I never found any - are they hidden that well, or was that unimplemented? Only having three hearts felt quite punishing by the final room. Anyway, this is certainly one of the games in this jam I played the longest, good job.
