Fantastic work!
This game heavily reminds me of Downwell in terms of mechanics and visuals, which is a good thing. The game was decently chaotic, though I feel like everything was a little too slow for my tastes.
The idea of a bullethell where your bullets can hurt you is really smart, and leads to some really interesting gameplay. The enemy spawining system is also super cool.
I'd love to see this expanded into a full release in future, amazing work.
