One small bug (already mentioned in some old threads).
If you move screen using A and D keys it sometimes jumps directly from one edge to the other (doesn’t go smooth as it normally would when moving the screen). . . Mostly happened if I hold one button for some time (second or two while already on that edge – shaking screen) and then immediately pressed the other one. Happened sometimes even without edge trick when I just pressed A or D while in the middle of level but that way it happens rarely.
And also you are unable to move the screen (any method: AD, arrows, mouse on edge) if mouse pointer is somewhere in bottom 1/4 of the screen.
Don’t know if intended or not but on level 37 you get more bombs than needed to complete the level. No need to start with a bomb as you pick up one right at the start and that’s all you need to pass the level.
