Most likely due to wrong magic numbers in fog calculation.
This game uses exp2-distributed fog intensity, so scaling the exponent by 8.f instead of e.g. 1.f is very noticeable. Using 1.f instead makes the fog look less extreme.
Guess I'll have to carry out some tests on real hw to find the optimal value.

Please provide a save file for the game and steps to reproduce the issue with minimal effort and without assuming I've ever seen the game in action. I'm running the game at 10 FPS and really don't want to play through the first few levels just to see I've done something incorrectly.

Simply load up on save on this GC mem card, and select level 6.
