Thanks for pointing these out! I'll address your points in the order you presented them to me.
- I'll work on including a full-screen option either in the next update or the one after. It's important, so thank you for drawing my attention to it.
- I'm not entirely sure what you mean when you say only two menus are accessible via the Escape button. The main menu and the menus it connects to should all be accessible by clicking on them, and pressing escape should either return you to the main menu or the rewards screen.
- Holy crap, not being able to move is terrible! I believe I may have fixed the problem, I'll push out another update tonight and try to test it in the morning.
- I have a pretty good idea I know whats causing the problem with the spider being camouflaged. I created a skin called "smolder", and it appears to be a bit hard to see. I'm currently replacing it with a somewhat more boring, but easier to see skin.
Thanks again for telling me about these problems!
