I decided to upload my personal Dev Demo to rmn. There are a few things to note:
I may have left some cheat events in the game (testing purposes only, if you're a game dev you'll understand).
I left some saves. Feel free to use those if you're stuck, but beware. I play on Warrior. Equal to hard.
Anything after Hogrothan is heavily indev. Some areas don't even have enemies.
Also, I'm using bullet-xt's audio engine so you must use "Start.exe" or it will give an error.
