Really liked this entry! The puzzles are really well designed with the right amount of challenge. Though the final screen with the relic could've used a checkpoint or two imo. Was pretty close to ragequitting when dying on the spikes at the entrance after finally making it the whole way back. xD
The art style is really nice and the audio fits well. The only other nitpick, is that I wasn't too keen on the swimming mechanic, luckily it was only a tiny part of the game. :)
Great job!
