Thanks for your kind comments. The game is 540x960, I didn't have time to implement dynamic resolution. Did you fullscreen it to make it work?
Web build eventually loads, it takes a long time though because of the level backgrounds.
Options menu is not implemented, and I actually removed it on the web build.
In general the last three days of the jam period I was away on a business trip, so I didn't have enough time :)
Thanks :)
