I had no idea what I was supposed to do. But, I had a simple please on killing myself with rocks. Ironically, the rocks behave more like boomerangs than the actual boomerangs do.
Wanna try mine out? https://itch.io/jam/xkcdgamejam/rate/196038
Agreed it is a concept that could be developed further and I hope you do! Anyway one thing I do want to mention is I'm doing a review of design on the games in this jam so here's a shameless plug to my channel if you want to be notified of the vid when released: https://www.youtube.com/channel/UC7Vj46GGL9VMUvd4YTMtjXg
My XKCD game jam analysis is out!
Ha ha, yeah fixed the rocks and other stuff, and added a few things too. Like a pause menu that tells you the objective again.
I was about to go play your game but I am on a mac and there is only a windows version. :'(
