I just released my small casual balloon simulator, you pilot a hot-air balloon tiny planets, and throw parcels at stuff *ahem* deliver parcels to the residents. It was my LudumDare53 contribution, but time didnt permit me to finish until now :)

Currently its for MacOS and Linux, but building for webGL as of right now.
