I really enjoy this humble throwback to the flash games of yesteryear. It has that old-school edginess reminiscent of icons like Pico and Eddsworld with some snappy dialogue to make it feel both familiar and fresh.
For gameplay improvements, I would like to see a map feature to make exploration easier when the full game comes out. I would also like the option to change the button prompts for gamepad to PlayStation or Nintendo. Maybe allow for twin stick aiming as well if it doesn't seriously break game balance.
I look forward to seeing this lovely project of yours become something amazing.
