Nice job! I think you've progressed a lot since your first demo. Movement feels a lot better. I couldn't beat the boss though, maybe add some kind of invincibility after you get hit because it's pretty easy to get juggled by the white things he shoots out. I don't know about others, but I had a really hard time just getting it to 75%.
I ran into a crash after repairing my armor and heading south. This was after going to and from the lake several times. No dev commands were used.
But overall I enjoyed my time with it! I'm really looking forward to seeing you continue to expand on it.
It happened around here. I had went to the lake, returned to the castle, bought more health, and it crashed as I approached the corner.
