In this demo I used my c_pixel library. This dealt with nearly all of the pixel related stuff in this demo. For example, it allowed me to define the collision box of an object by setting its x1, x2, y1, and y2. I also used my Pixel Mouse Drag demo which allows me to drag on a tile, pixel by pixel. (Both the library and demo have not been released)
I know this demo is quite choppy at the moment as there are several bugs in this demo, one is with the movement. Pressing right and left and then letting go one of the keys will sometimes make you run faster. Also, switching from left to right, or vice versa, very fast will not allow you to move. I know how to fix these problems but I am far too lazy to do so at this moment. I also cannot find out why this bug occurs, but randomly the game will crash while jumping on the spring box.
Hopefully I'll finish this game one day, I like the concept and potential. I can see a huge community in which they create challenging maps. Have fun with this test demo!
Controls:
Arrow Keys - Move
Left Click - Draw Line
Right Click - Erase Line
P.S. I'm still working on the concept I posted two days ago, I just wanted to stop this from rotting away on my desktop.
