Ok, so good news. I found out that I can actually extract the game with 7-zip. Jonaz O. that's an EXTREMELY important detail that from what I can tell you haven't listed anywhere. Please put that somewhere on your game page: https://jonasz-o.itch.io/fallout2remake3d
Anyways, unfortunately I ran into the same problems with the windows version, and this game is still unplayable for me. I'll try to move forward, and I'll randomly either move very slowly, or even worse move backwards very quickly, often getting pushed through walls and have to reload my game.
I also still only have 5 action points instead of 8 despite giving myself 5 agility.
Also, your enemies feel a lot faster than you, and their attacks always seem to hit you, making this an extremely hard game.
I'd appreciate if I got some sort of response.
