Right now I have had a total flood of ideas! This is good.
1.The main menu will show clips of each level that you have unlocked or all levels (i'm not sure yet).
2.I have thought up a model for the fire gun!
3. have finally decided on the back story for some of the levels.
(This is the most important)
4.When I have finished tier 0 and tier 1, I will release them as a demo so people can test it and I will then release the other levels in the finished game.
