I loved the absolutely gorgeous settings menu.
Music is great, but would love to see more sounds and maybe main menu theme.
The akzelotl flying dragon is way too difficult, pretty much impossible, you can't really evade its attacks, and health bar is very mysterious with different colors and everything and there are two of them and nothing is explained and it's invincible.
Now the bigfoot is very easy. Hunter easy cools it. Bigfoot has one stupid attack. His brain must be as big as a grain of sand.
If you say you have open source, you should link to it. If you say "some may be open source, but I dunno" that's absolute bullshit.
Credits menu is outrageous. "Person1. Person2". What does that even mean?
