Yea, I think the 100% achievement is buggy got 93/93 and all emeralds, and all achievments but the 100%. No win screen. Did the secret questions last, and got all the emeralds before the last secret question.
It seems that no matter how fast you ascend the moment you let yourself slide back down the tracking laser shows up at the bottom of the screen. This seems to contradict the instructions that the laser speeds up over time. I can ascend 200 meters in a few seconds if I'm lucky, slide down and bam the laser shows up but if I ascend the 200 meters in more like half a minute I haven't been overtaken by the laser.
This game would be better if the targeting would actually make sense. Ninjas would switch sides just cause two enemies showed up on one side or another enemy showed up just before the closer ninja killed their target. Also what good is setting one to defensive when they let an enemy start attacking the blind girl because one of the other ninja's is walking back to attack it?
