Default controls:
WASD - flyin
Z - shootin
You can switch to mouse or pad controls in settings. Pad controls might be weird, there are 2 modes, because I don't know what's more natural for games like these.
Known issue:
Enemies (sometimes?) don't respawn when they die due to floor or ceiling.
What's new:
There's audio now, new sprites, some unfinished upgrades. This is the first time I feel it's in playable state, thought there isn't much content.
If you have the means, please test playing with gamepad and leave feedback how it works.
