Thanks for feedback!

There is no hard ending. You can unlock some doors and gates with consoles (the idea was that you'd be contacted by security over radio, and they'd advise you on how to progress), and eventually arrive at the hangar where a boss fight was supposed to take place (and an ending cutscene), but right now it's just an empty room with glowing text that explains how the ending was supposed to play out.

Thanks, glad to be an inspiration!

You mentioned controls, maybe it comes down to past experiences? What you describe sound like controls for a tank or a car, where W means forward from vehicle's perspective, meanwhile I've mainly played top-down shooters where W means up from player's perspective *shrug*

Thank you for your kind words! I had more content planned in my mind (enemy types, character abilities, radio chatter) so it should've been more variable, but those didn't make it in. Actually, level length is not something I thought about at all when designing it, but now that you mentioned it I'll have to remember it, thanks.

The smoothness comes in many parts thanks to 2D physics interpolation. You have to explicitly enable it in project settings, and take care of what goes into `_process` vs `_physics_process`, and cancel smoothing on case-by-case basis when spawning/teleporting entities. It takes some non-zero effort to keep it bug-free, but the visual payoff is great, especially on high-frequency displays.

Thanks! I'm happy how it turned out myself, the lighting gives a lot of "pop" to the otherwise mediocre pixel art, lol.
