full changelog is here: https://mysteriousspace.com/changelog/0-10-x/
but before I summarize: there's a bug I've been experiencing on my computer, but haven't been able to reproduce anywhere else: in fullscreen mode, Mysterious Space runs SUPER-slow! unplayably slow! I've checked with a couple other people, and a couple other computers I have access to, and so far the bug SEEMS to be isolated to my computer...?? strange...
if you also have unplayably-slow framerates in fullscreen, please let me know!
ON TO THE CHANGES:
* eliminated more instances where you'd start a level RIGHT ON TOP OF A MINIBOSS. because that's super uncool.
* a new enemy: Wezen Web-walker
* a new accessory: Stasis Field Generator
* a few equipment & subroutine tweaks
* some Ocean worlds are now narrow and super-deep (I thought about doing this for Lava worlds, but that was too mean :P)
* made some improvements to the internationalization/translation code, to allow for more-complex string replacements. thank you, fedprod, for suggesting this!
