That's awesome, thanks so much for making and sharing this video of my game! Definitely the current version (0.2.2) contains more varied gameplay, with different room designs and the fire demon to contend with. But it's still an endless game that's all about clearing out floor after floor.
When making games I tend to focus on the gameplay mechanics more than anything else.
Your video has inspired me though; I think I'll try to give it a bit of a restructure so that there's an endless option but also something that you can win and put down again.
Still it's great to hear that you found elements of it satisfying. I hope you are able to get around to giving it another try sometime, with the current or future version.
