I'm glad you got the save working :). I am not 100% sure if more updates will be made. I would love to keep working on this game but other projects sometimes get in the way. We will do our best!
Cheers!
Thanks for the feedback. We noticed that the save system doesn't work in certain web browsers, probably because of safety and security reasons. We did try it in chrome and it has worked for us.

The save system was the most important feature that we added so it really sucks that it doesn't work for some people. Concerning the grind issues, yes we do know that parts of the game feel extra slow due to the long time gap between upgrades. If we can find the time, we will update the game and fix the balancing even further.
