@NewJorg was asking me for the build of the game and I realized I never uploaded a build because the game was always unstable in the main menu.
So here the old build that was simply recompiled with the new SDK.
Doom.pdx.zip (2.2 MB)
And here is the full project
DoomProject.zip (6.4 MB)
The game is still unstable and there is no sound. After this proof of concept I basically started again using Doom Retro this time as a starting point but soon after I simply drifted away from the project. I will try to go back to it now.
