Just wanted to say I'm SO PROUD of everyone who participated, everyone who submitted a game and everyone who tried! Such a great movement!
Wow, I literally just figured this out, too, after hours of playing around trying to narrow down the problem. Yep, it's the terrain. If you're also using the URP-PSX shader, it's putting the shader on the terrain that causes the crash. Exporting seems to work now with normal textures, but I think building the terrain from scratch is probably the better option.
Congrats to getting them all in! So much talent on show, constantly amazed! I really loved being a part of the jam and I'm loving going through them all, thanks for letting me join in! I also had a game breaking bug on release day, all my dependencies started pointing to non-existent prefabs in the final push! Had to literally go through every dependency in the project and relink it, still have no clue how that happened, but its always the way xD
