Oh gosh thanks for letting me know! Can you tell me which browser/OS you're using? You're right that every time you reach a yellow gate you should be seeing a different map. Unfortunately I couldn't repro this on Windows for Edge/Chrome/Firefox right now.
It was Firefox for Linux, although I just upgraded to a (slightly) newer version and it's working now, so that's odd.
I like the game. Having named party members that you can get attached to is always a nice feature. The balance seems a bit tough (I feel like I didn't obtain potions quite quickly enough to feel like I was making progress on par with the increasing number of enemies), but that's to be expected for a jam game. But I had a lot of fun playing this, and it's definitely a fresh idea (mechanically & thematically) while still being a classic roguelike, which is neat.
