Ok, at one down, and I,have a good idea of the direction this is going. I have abandoned the original ideas of the artist, and have opted for a more Arcady, action game. Levels will be procedurally generated, with a plethora of weapons at your disposal, along with monsters, and bosses.
I have already built the level design engine and the player movement, gunplay, and progression through the levels of the void. I also created a main menu and an beginning splash screen section. All sounds and music are accounted for.
Hopefully tomorrow I will have screenshots, and/or GIFs to show off, but until then, happy jamming!
