Yeah I suppose using Unix layout doesn't really do anyone many favors (Caps-lock as Ctrl lol), I am sorry that was your experience!
Anyways the enemy health spike is somewhat intentional as the intent is to encourage you to avoid fighting higher tier enemies whenever possible since you are supposed to be relatively feeble (like a souls-like but without the getting stronger part basically.) Had I more time I would've used it to add more tools to handle obstacles (it was supposed to be that higher tier enemies could only be incapacitated and not outright killed unless you met certain conditions or had certain weapons.), but I burned a lot of time just learning how to make Unity do stuff.
Although yeah there are a lot of balance problems and outside of making sure you could beat the game (passing level triggers and the boss fight working), I did not vet anything very much!
I admit, I had planned for something far more ambitious than I realized I had time for...
Thanks for the feedback though!
