I'm going to agree with Pack A Punch in response to the discord conversation and say that download games aren't going to get a lot of feedback. It's an extra step people need to follow. Not only that, but you're already feeling dubious about running a random .EXE you find on the internet and then you get hit in the face with:
[That's the "Windows protected your PC" image. I'm not sure it's showing up here]
.. and then it's at least 2 more clicks reminding you that you're running someone's random, hastily made, hopefully not malicious software on your PC. If you want more feedback, web games are better. Even then, you probably want to seek out smaller groups than a 1000+ person Jam. Or just do it to learn. (I don't really do it for feedback so much as to expand my skills and to have fun collaborating with my kids)
Anyway, as to feed back for your game... I liked it. It had a fun and consistent are style. I'd say my main criticism was you were probably better off picking a single button, and then being open to allowing at least the escape key or some better interface for when I wanted to stop playing. I wasn't sure how to close the thing. I only played it a few times, but at times it didn't feel fair. Fast moving enemies and a fixed speed on the shooter meant I felt a bit frustrating.
