Itch.io build doesn't seem to work for me, but was able to play by clicking 'download' on the link in the game's itch.io page and it opened in my browser.
I had fun experimenting and figuring out how to get up to the sword. After getting it though, wasn't able to figure out how to use it... i think this could benefit maybe from some sort of hint system deployed over time, if the player is meant to discover how to play. Or maybe just a little more scenario context in the opening. Also I think a timer display would be a good addition.
