+[M] Save score on per-level basis to make high-score
+[M] Save time on per-level basis to make low-time-score
+[M] Add bonus score for extra time left when finishing a level
+[M] When aborting a level, lives and score should remain the same as they
+ were before. Solution: make more dependency between the game engine and
+ worldmap or just backup those variables before starting a level. - fixed?
+[M] when bumping a special with 2 blocks at once, it won't change direction
+[M] tux get killed if he kicks a iceblock while at the same time bouncing on
+[M] You shouldn't be able to stand on invisible blocks, before you bumped them
+ the roof
+[M] bombs should explode directly when hit by another bomb or a mr.iceblock
+ - right now they transform into a "squished mrbomb"
+
+[L] Allow any object to be inside of a [?] box, ie. trampoline or badguy
+[L] in the "Welcome to Antarctica" level, the blocks next to the first growup
+ look like there are 2 blocks above each other when bumping against them as
+ small tux...
+[L] time runs while being in in-game menu, at least a bit (jump, go to
+ menu, wait a bit, leave menu, Tux will 'flip' to the ground,
+ instead of fall, pause mode doesn't seem to have this problem, only
+ menu)
+[L] catch exceptions thrown by lispreader
+[L] fadein/out for intro/extro would be nice
+[L] we only have a global counter for multiple coin blocks. This should be handled
+ per block.
