Absolutely loved the playing this game. The polish on it makes it feel like a paid Steam/EGS release. The artstyle is very consistent, the writing is witty and fun, and the difficulty, while being challenging (holy crap that first boss), is quite satisfying to overcome.
The only small nitpick I can think of is that the flying mechanic seems a bit... useless? The tutorial makes it seem that you'll need to fly to traverse the levels, but the game itself is perfectly beatable without utilizing it all.
Overall, great game. Would recommend to everybody!
P.S. What is the final boss doing in hell..?
