Remove lagg.

[Watsamax1]

My RPG style game currently is about 130 mb's and it isnt getting smaller. Ive tried removing events, and making methods for everything. But not i still need collision that works fast, walking that doesn't lag somehow always messes up . And combat, and another world and a dungeon. so as you may see my game will be laggy then and i still need some building collision for a few buildings.

So any ideas on how to remove this lag will be appreciated.
