Now I'm just trying to separate different game sections, like the main menu, the menu where you choose levels that you want to replay, the game itself, the game over screen, the section that restarts the game, etc. I'm trying to get the basic architecture of the game planned out basically. For this I am using some temporary sprites just so I can test if the mechanics work.
Thus far I've made a temporary main menu:
And a temporary "choose level" menu:
For an artist of my caliber the 3D buttons look pretty neat (if these were the early 90's). The bloody stain is also a temporary asset with which you choose which level you want to play and press space to engage it.
