Thanks for trying out our demo!
We're aware there's a lot more work to be done to make the game much more clear, specially in the field of audio cues and finding the next objective. Currently, it seems a lot of people are getting stuck in the key carrying part, so we'll probably switch that up a bit since it's not intended to be taken as a puzzle, the challenge is in carrying the key itself.
As for enemies, hopefully better audio cues should help. For now, I'd recommend trying out the dash some more, as it will damage anything in your path while launching you forward!
Thanks for playing and dropping us feedback!
