My son and I were playing a game called barrage on my old linux laptop day before yesterday. It’s a very old laptop so only old low graphics games run on this machine. We liked barrage. It’s a simple tank shooter. There is a gun positioned at the north-west of the screen, and the screen itself is a battle field and tanks come from the north or south and cross the field. You have to position a mouse crosshair and shoot as many as you can.
Simple game, I thought I can recreate it in a few days …
