Thanks for trying it out! :)
The "roguelike" is not really there because it didn't get done in time. The school part is working but the world really isn't. I also admit that the ping-pong is probably too harsh — there was little time to do balancing, so I just put some numbers in there and that was it :—). I was working on it with my brother (who wrote all the stories) and scripting all of those things that he wrote took me way more time than I thought. In retrospect, I should've sacrificed half a day or even a full day to making a simple GUI that would generate the scripts automatically. That would be a huge timesaver for me and for him as well.
By the way, the graphics is all Creative Commons and there is a complete list with attributions in the zip file, so you can have a look at where exactly I got it and under what terms it can be used.
