Tight corners could get really unconfortable but there is no reason to add sections with even lower height ;)
Right now there are 8 sections and they are chosen randomly. This is just a test bed right now. When I get more environments, both with new generators and just new variations of existing ones, I will change that to have whole levels with a different mood and pacing. Some will be full of shooting enemies, others will have turrets etc. And the looks should be more consistent throughout a level. Now it is just all random stuff put together.
About the bugs:
1. It would be great if there was a chance to send me a log although I expect that it might be hard to track that particular logfile. Did you have such bug earlier or was it introduced lately? I expect it to happen in this or only since the previous version. I was changing how equipment is generated for the player and I could mess up something. Good news is that the weapons generation system is one of the things coming in following weeks. I plan to do modular weapons and the generation of them will be changed (code-wise too) so the bug should go away then.
2. This seems that it doesn't blend it properly. It looks that instead of blending a blurred version with a sharp image, it just renders the blurred one. At the start, there is this booth and at the side there is a screen with an arrow. Does the arrow look ok or is it blurred too?
