I started this project initially as just a recreation of the Isaac room generation algorithm, as I was interested in how it worked behind the scenes. I soon realised it would be really helpful to have a tool to practice my knowledge of secret rooms with, and from there I got the idea of a daily game. This site has both - a daily challenge and an endless mode for practice.

The algorithm should be quite close to the game, so its a great tool to build an intuition for secret room locations! It's not a 1-to-1 recration however so be warned. I hope you have fun with the site, as it was a lot of fun making it : )

If you have any feedback, bug reports or feature requests please dm me on reddit, feel free to check out the github to see the spaghetti code, and if you're feeling generous you can support the site on Ko-fi.

I have recently added google adsense to the site - I'm sorry for the inconvenience! It will help pay for the yearly unkeep costs of the domain. There are no further planned features at this point, but I may return again if I get inspiration or think of a really cool new feature. I hope you have enjoyed playing for the past year and continue to enjoy for many more to come!
