I tried the version that was found here. I didn't even know there was a newer version. That's the problem with jam games, most of the time you don't even go to the actual game page! I'll check it out.
I really enjoyed it, really. I actually would like it to get 20 ratings, because I think it should be featured in Brackey's post-jam video. It's pretty interesting and polished. If nothing else, the graphics need to make it in! :)
I don't know how to change people's opinions about the roof. I really liked it and it was super useful, but it did feel like an exploit at times. If you added some text somewhere saying that it's not a bug, it's a feature, then I think people will be more receptive to it.
Good job! And good luck working in future versions of the game :)
