Cool concept and hilarious ending.
1. Using the sword to get out of the top-right cavern after gaining double jump was downright unenjoyable. That level design should be adjusted or the combat should be changed. As it stands, that part as paaaainful to play.
2. The core mechanic of packing your abilities in to an active loadout is very cool. However, you didn't let the player explore that at all! The only time that mattered was for using double jump at the very end of the game. If you're going to make a cool core mechanic, you should lean in to it as the main thing you want the player to engage with.
Other than that, this is a nice little piece. Thanks for sharing it!
