Hey! The DOOM feeling is something I'm actually planning to evoke so I'm really glad that it shone through for you. It's partially inspired by many boomer shooters (specifically, the high-octane movement) to give rise to this sort of pinball-esque gameplay. I'm really happy it resonated with you.
Thanks a lot for your other pointers too, something for me to keep in mind! Appreciate your deep input my guy.
