I know we were talking in discord when you wrote this but I still feel obligated to respond to all comments.
Thanks, part of the content we had to cut to release it before the jam ended was a time rewind. There were a few gameplay ideas with this but I also feel it would serve as giving you an undo option quite nicely. In a full release we will likely try to include this. As for the crashes I've found it has crashed a bit more than expected. There are a few reasons for this all of which will be taken care of in a full release should we put one out. Part of it was just trying to make the game look so good that optimization suffered and there were no options to make the game look worse to run better.
I'll lower the default volume next time. As for settings in game that was because we had two different programmers on main menu and in game pause menu. Totally something we should have fixed though. Sadly we didn't have the time for it.
There are a lot of things I want to do to bring that execution back up and get it more polished. I think my team managed really well and we were able to get a really cool product out but we may have been a bit too ambitious. The original goal was first 24 hours spent on the core game and the following 24 spent on just polish. It ended up not being that clean.
Anyway, thanks for the feed back and hopefully if we full release it then it'll be a lot better. I did quite like your feedback on needing an undo feature and how that works really well with one of the ideas we had but cut.
