Very cool game. Unique and fun movement mechanic. Interesting to explore. It'd be nice to be able to teleport to already reached buckets to make going back to get shells a bit easier. Got 7/12 tonight, going to go back and try to get them all!
Thanks for the kind words! I wish I'd had the idea to add that sort of fast-travel, I agree that it would make backtracking much easier. Good luck with getting the rest of the shells!
