Really fun, it does keep your desire to replay the game burning! The talent tree thingy is the one responsible for this, along with the loot boxes you find around there! I wish the boss fight, with the Doom music in the background, would have been finished, it looks amazing :D
Issues:
- no idea how, but the first time I climbed onto the arrows to the ledge I started flying and was able to bypass the whole map and get to the end of the level x)
- you cannot quite get back to the main menu; if you want to change the level, it ain't gonna work, especially if you do it from the fire level
Awesome work!
