Thank you for reporting the bugs! I'm glad you enjoyed it!
I'm really not sure why the game crashes - were you playing on browser or did you download it? I think both crash if you go too fast for some reason. I'll look into fixing it.
The computer UI clicking bug is also noted. I intended to fix it but had more pressing things to attend to so that slipped away, as with things that happen in jams!
Glad you liked it and thanks for helping me with nav3d nodes!
