Last week when we created our haunted house, we decided to turn them into a small game. Chris made us an engine which already code in, however they was some bugs which was left on purpose. We had to adjust the code which made the character move left and right. All we had to do was to switch the code around, we could also change some of code like the gravity and speed.
I also made my game bigger, I used the resolution 1080 x 720. This would allow me to make the level bigger, thus adding in more features.
