Please, do not use rar files for linux builds. They are more annoying to use than simple .zip files.
Also, files starting with a . are hidden by default on Linux. Took me way longer than needed to find the binary to run it.
As for the game itself, I didn't get the point of bugger. Seems like I can go through the walls and that it sometimes doesn't eat the leaves. Going out the screen also doesn't seem to have any negative effects (Or at least I didn't spot them).
As for the pong game, no idea what causes the bug that the ball goes through a peddle and the ball also got stuck one time. No idea if that was intended or not.
