Oh wow, thanks so much! I'm glad you played it and liked it! Since we're all figuring out how to use bitsy together, I'm gonna share my secrets right here:

• Bitsy rooms can have two-char "names", I'd guess going up to zz, so that's 37*37. (though this game only has like 70.)
• For the warping, I used a great hack by mildmojo (thanks section in the description) which I put into the html file generated by bitsy
• By slowed down animation I guess you mean the avatar? That's done by using a little trick that someone in the discord found. (Ithinkit was mildmojo that did that first as well, for their midnight jam game.)  Basically bitsy has built in support for multi-frame animations, but you have to type it into the data window directly. So it's actually several identical frames in a row that simulate a longer/slower frame.

It was really fun to make this game (although I was a bit tired of it near the end, as you can maybe tell from the final battle) and I'm so so happy that people like it.
