Nice game you made! It reminds me of the first 2 fallout games I used to play, the camera controls were a bit hard, maybe add mouse support for the camera, the music and overall atmosphere were fitting, I like the little particles flying around, the graphics were minimalistic but well executed, I was stuck for a bit trying to shoot an enemy, but i wasn't clicking on the square the enemy was standing, I was clicking the 3d model, you've done a great job as a solo dev for just 3 days, well done! :)
