Wow! Thank you for the comments on the technical aspect - I definitely put some hours in to this one
Its Unreal 5.5.3 (blueprint code) but as you can tell, I made an effort to really try and have the retro vibe. Turned down settings, disabled features and textures are I think max 128x128... mostly 64x64 (made with an app called Wally). Than 3D models, rigs and animation were all done with the internal Unreal Engine tools.
Thanks for playing!
Edit: Also most textures were Unlit - I still used Lumen that created a bit of atmospheric fog to the world/sky but pretty much no dynamic / global illumination lighting.
