Hey Michael, love the starting, love the sound.
Mushroom sounds weird (is that you?).
The first time I saw the mushroom man I tried to jump on his head (I had no weapon yet), since it seems like the platformer intuitive thing to do and his head is so inviting.
If I haddn't already seen you can jump on the pipes on the house I might not have tried.
The key only appearing after speaking to the NPC is a bit upsetting for me and I feel it would be better to gate the sword off by having the mayor yell at your or something. It also wasn't intuitive that chests need keys.
Overall, enjoyed this very much and will buy the final release for sure!
