Thanks for the feedback! I have already rebalanced the game, though I still have to test a few things and wait until the judgment period of the game jam is over to post it. The main changes you will see if you play it again are:
- Unlock automation much more quickly
- Rebalancing of each currency (Lower upgrade requirements, less silver [grey can] income)
- Much less extreme upgrade requirements
- Automated ads (if bought, ads will be automatically closed by a different cursor). Also, ads will tend to get shorter each time you play them.
This game has become insanely popular compared to what I was expecting, so I will be focusing my efforts on it. Expect an update within the next few days :)
