Tengoku Gaiden: 黄白機 ～ Submerged Machine of Deepest Desire

Still at the beginning, but I noticed that itch.io selects the first version corresponding to your platform in the list by default. Could you try to move the jam hotfix version up and see if itch decides to select it as default install on Windows? I’ll also try on my side on my own games, I realized I also have a jam and post-jam channel so it may be worth making the post-jam default too.

Otherwise, the Windows Jam hotfix build is running fine on my PC. The web build is running on Linux + Chrome and Windows + Chrome, but is failing to start on Windows + Firefox. The console errors do not mention SharedArrayBuffer, but blocked loading for Content Security Policy, so I suspect Cross Origin Isolation.

EDIT: I kept playing the Windows build it has lag on massive bullet spawn, making it harder to play and dodge at critical moments. Oddly enough, I have the impression the web version on Linux Chrome was smoother? I’ll try it again. Are you spawning your bullets by adding new nodes? I know Godot should be performant and not necessarily need manual pooling everywhere, but in this case maybe some sort of pooling could help. I haven’t checked how other bullet hells in Godot work, so not sure.
