Thanks for the comments. I will consider attempting to make a video. As long as I can get footage that doesn't appear to lag. The enemy sprites are from various sources, while the main character is a custom franken-sprite. However, the animations for the player were all created by myself.
Also, I'm afraid you're mistaken; I'm not using a lighting script. That's actually a good old fashioned event, showing a picture. I prefer eventing if possible, the fewer scripts I use, the less they interfere with each other. Anywho, it doesn't lag; and that's only in the dark cave areas. Use the lantern to illuminate the darkness, and also ignite enemies/torches.
Edit: Added a video. The video quality doesn't really do the game justice, and the video lag doesn't exist in the game itself, but it'll at least give you an idea at what the project is like.
