I'm sorry there's a bug with the viewport. Currently, bullets are supposed to despawn when they go off the screen. However, it seems this feature works only in fullscreen mode with F11. I'm working on rewriting the code to address this issue. The fix will involve updating the logic so that bullets despawn when they go outside the level instead of the viewport.
Edit: - Fixed
Got to play it all now. Worked really well everything. I loved the swarm controlling gameplay that is almost more about positioning then aim. The boss was really good and not to hard with observation. The music and the atmosphere are really great too, really an enjoyable ride against the metal swarm.
