So this is a fun game, but I could beat it without even coming close to upgrading everything. The difficulty ramp is not quite right. Other than that, quite nice.
The controls are terrible. My guns continually shoot and I can't stop them, so I have to use nothing but melee. I can barely aim... atrocious coding on this thing and doesn't deserve badges.
Okay, I figured out that using the keyboard to fire and the mouse to move caused the "side laser" glitch. So... don't do that. Use the mouse or use the keyboard, not both.
Also, another issue - when you use the mouse to move, the "side lasers" go up to the top of the screen and are essentially useless. The mouse controls need work.
This game is fun, but the controls are terrible. You have to make sure to keep mouse focus or the ship goes flying up to the upper left corner, which usually borks the run. The weapons are a bit janky too. 3/5
Why does the button to upgrade my plane not work? Why does my plane jump to the upper left corner when it loses mouse focus? This is very irritating to me.
