The premise is interesting, but it has a lot of bugs that could potentially softlock the player.
First run I tried to play as Haley, but couldn't get past the sliding ice puzzle. Probably just my fault, idk.
Next, I tried to play as Dayna. Made it all the way to the volcano, but then got a "Failed to load img/characters/%24BigMonster1.png" and couldn't progress any further. Well, at least what little of her route I saw was funny...
Finally, I tried to play as Ruby. First run I didn't press the switch in the red chest the first time I opened it, and when I realised I probably should have, I didn't have the option to press it again and had to restart the run. Same issue with the puzzle with the purple flames. Made it all the way to the volcano, then used the teleport spell with the coordinates from the previous area, and got teleported to some other volcano map where I was stuck with some guy whose image was permanently displayed to the screen, and could do nothing except teleport to the same location... Kinda gave up after that, tbh...
