The procedural generation of maps was one of our major points that we wanted to put in. Glad you enjoyed that.
About the other builds, for our next version of the game we will upload other builds aswell. Sadly we currently are not allowed to release a web build that is based on the submit commit. We learned a lot in our first game jam and hope we can translate a lot of our learning into our next game jam. We already talked about the next one.
