after shooting the initial fluffy dudes on level 2, they tend to diminish to just 1 hostile, and then to none. Not sure if this is just a v2 thing, or if it was like this in v1.20 as well. Just noticed it now. Also on level 3, the objects that drop from the top began to get stuck at the top of the screen.
Level 3 is okay now, but level 2 still has the aliens not respawning after shooting them a few times, leaving the battlefield empty while you fuel up. Also Level 4 after losing a life, jetman doesn't respawn to continue playing. Also on the main menu now, option 2 also starts the game. On the game over screen (when I died before lvl 4) it would not return to the menu. Nice work on adding the controller support, if you choose no however, it still enables controller, and keyboard doesn't work. I noticed your comment about not wanting to tinker with it to much, as it may break. Seems it might have a little bit. 👍
