Thank you for your detailed feedback, really helpfull! If the sun is a square in Minecraft, why not here? :D. I actually thought of the idea of implementing gravity near the sun, but for me it was too difficult to implement with the limited time I had. The RMB shooting is a leftover from a earlier version of the game. Originally, you had 2 weapons: a pistol [LMB] (you can still see on top of the firetruck) and the water cannon [RMB] which is still in the game. I removed the pistol because fighting burning sun enemies with water felt right instead of shooting random bullets.
