well, after spending 50+ hours counting the spikes in the game, i now know where they all are, and the % of where each one is at.
7612 in all
Space Station - 7.12% (561 spikes)
The Laboratory - 27.32% (2152 spikes)
The Tower - 10.47% (825 spikes)
Space Station 2 - 27.15% (2139 spikes)
The Warp Zone - 6.07% (478 spikes)
The Final Level 13.09% (1031 spikes)
Intermission - 2.88$ (227 spikes)
free space - 5.9% (465 spikes)
37.1% pointing up(2824 spikes), 30.78% pointing down(2343 spikes), 15.95% pointing left(1214 spikes), and 16.17% pointing right(1231 spikes)
i actually thought the game had more, but no, only 7612 spikes...i wonder if someone can make a custom level that has more...
