Catrap is a puzzle game for gameboy. In it you dig paths and push blocks in order to reach and defeat all the enemies on each of the 100 levels.
This is an ~55 second improvement over the previous run, the following levels are improved with strategy improvements:
24 - 7 seconds
35 - 1 second
39 - 1 second
43 - 18 seconds
45 - 5 seconds
65 - 10 seconds
75 - 2 seconds
78 - 5 seconds
91 - 1 second
95 - 8 seconds
Additionally, several levels were improved with small movement optimizations such as going down ladders before falling or pushing blocks in different orders to avoid falling animation.
Finally, a glitch that was present, though apparently unnoticed, in the first run is exploited in several levels. Normally when you defeat an enemy, you have to wait for them to despawn before changing characters. However, if more then one enemy is defeated, or an enemy is defeated and a block collapse is triggered, you have 1 frame when any of these events ends to change characters. You do not need to wait for all of them to complete.
