Ah I see, I thought it said it as one of the main rules. Usually game jams are web games that way people can play them without the possibility of downloading a malware.

Yeah I am also familar with that concept - that's how my recent game jam submission also was handled. Though for this one it was only optional, so I thought why not make an actual good 3D game with some story and stuff instead of making the next browser cookie clicker but with water this time lol.
Have you played it though? Or were you scared of getting malware?
