I really liked this take on the theme and you really designed your mindspace to in a great way. The background ambiance was a good touch to showcase the anxiety as well. Also, I didn't expect a game jam submission to allow me to toggle all the SFX, background, and mouse sensitive options. That was a great touch!
I did feel the game was a bit too intense at the start. I was just getting the hang of the controls and then about 100 enemies spawned which was a bit overwhelming. Regardless, the controls felt good, the in game dialogue was great, and I had an overall great time playing. I think if you added some more 3D models it would be an awesome game to expand on. Great job!
