So, the enemy AI is a bit messed up. It's basically impossible to kill an entire group of them, because they have so much health, and there are so many of them. The AI are really fast, and they track you, which makes it impossible to escape them. I basically had to just die until I got lucky and moved another 100 or so units.
I forgot to mention I made it in 7 days for a game jam. The enemies are hard but certainly not impossible. I have realised that the difficulty curve is very unforgiving and will make some serious changes and additions once the voting for the jam is over, and I can edit the submission.
I appreciate you taking the time to play my game!
