This is my first COMPLETE game. Basically, it's a platformer where you try to get to the end of the level. As you progress, the level falls to pieces behind you. It's difficult, it can be played by 1 to 4 people at the same time, and it includes a level editor so you can save, load, and share levels!
I have uploaded this game to my website XHHstuff and i'm working on the indiedb submission (needs a video).
The wall bug could be caused by frame spikes (might happen any time, based on many varying factors - that is, some might occasionally or constantly observe it, some might never) if you use "basic/plain" frame delta time movement and collision techniques. That is, one frame the player is close to a wall but not close enough for collision, and the next frame the player is moved based on the frame delta (long frame = high frame delta = long movement). Then a collision is detected with the wall, which stops the player's movement. Unless this is resolved (move the player "out" on the right side of the wall), the player is just stuck in the wall.<br />I observed the issue in some of my early games, but I can only guess as to how you perform collision detection and resolving :-)
