Will this have mouse support, like the first Polybius Invaders did? Currently, it looks like the demo for this installment can only be played with a keyboard and controller.

i feel a very strong headache after this game, it hurts more than anything else. Is this normal?

Why do neither of the available weapons shoot straight toward the reticle? The perspective is already wonky, making it difficult to avoid attacks or even figure out where they are in relation to the player, so having to aim BESIDE the enemies' shots in order to it them just makes things more cumbersome and unintuitive. Maybe it'd be better to remake the game in an actual 3D engine (Unreal, Unity, Godot, etc.) instead of mimicking 3D in Game Maker? Or maybe switch to a zoomed-out third-person perspective ...
