Thank you for the feedback! I will check the placement of the enemies, although I don't recall oddly placed ones in the first 50-ish levels. Most likely some edge cases, where the raycast misses by a very small margin, so the game thinks there's no island there. Haven't seen a floating tank though. I hope it's not the engine behaving differently on different systems.There's already a minimum and maximum interval between fuel pads. I'll see what I can do about the levels with big island, as they're trickier. Tweaking and balancing the placement algorithm is on the todo list. On the other hand, there are stages with no fuel in the original as well, where you're doomed to die without prior knowledge 😀
