I liked it. It felt really nice just to move the character around, and speedrunning the first level felt really good!
It's unfortunate that beating it didn't unlock any other levels for me, so I was only able to play the tutorial and the first level. It looks like there were many more to experience.
One criticism I have is that it was hard to intentionally dodge the red bullets. The first level placed some of those machines in very tight hallways where even with slowmo it was hard to dodge them, and the bullets created additional red particle effects when they hit the walls which made it harder to tell where they were after they bounced. It looked pretty, but made it harder to play the game I think.
Overall, this seems like a fine entry for a first jam :)
