Yay the download link is working!
I'll come back later with my experience after tryin your demo.
I'm not the greatest mapper, but maybe I can provide advice on other stuff if you like. I'm getting really good at making trippy bosses now, so if you have any ideas you feel you aren't able to make work, just ask me and i'll see if I can't get them to work
EDIT: Played it all the way through. Forgot to fight the monster chest, so I never beat it, but so far this looks really promising!
I played with the keyboard and couldn't find the minimap, so I dunno if you intend for that to ve a feature or not lol. You may want to introduce people to the menu button and item buttons as well so they know where to find them.
Spoilers below! This is for Cubone unless you wanna spoil yourself @_@
I thought the boss was good, he's definitely gonna be difficult to battle without certain items. I noticed one issue though that I feel should be pointed out. My first try, I skipped the battle with the boss by accident and went right to the jail cell where Valerai gets locked up. By doing this I skipped the battle and got out of the castle area easily. I'd suggest that you set the event up in the jail cell to not play unless a switch is turned on, and this switch be turned on by defeating Valerai in his Death Code.
If you have any questions, let me know! ^_^
I think you're doing a swell job on this game so far. It has a nice difficulty to it. Just try to find a way to introduce people to all the buttons that they'll be using and other than the bug in the cutscene I found, everything looks great! It was really fun to play and I hope I can continue helping out
