I'm not sure why it's having an issue with starting, I also run it on Firefox and haven't been able to replicate the problem, but I will look into it and see what might be going on at startup. Thanks for letting me know!
It's just a jam game I made in 5 days, so it ended up being pretty low tension just to keep the scope manageable. I agree that more polished UI and and more rewards would improve it, some of that just came down to running out of time. Having a full map mode for less scrolling around is a good idea. Thank you for giving it a try, I appreciate your feedback!
