Super great game + it's your first game jam, a little story, it reminds me a little from hotline miami but less hard (and thanks god). Some minor issue but that can help improving, you should put an input to look further (alt or shift) just for the part where I need to go down. Miss some feedback too when receiving damage or when dealing damage. The mini-boss was a bit hard at first just because he can outspeed us and it was a small area. And for the final boss, it wasn't easy to understand, but when I saw the life bar with “factory” written on it, I knew what I had to do.
I see a lot says it's hard, i think it's not a problem, the respawn is fast, you have checkpoint, guys, try harder please.
