A weird bug presented for me. At a certain point (when purchasing my 4th blade, after having maxed Bouncy Disk) Bouncy Disk lost it’s ‘darkened because max purchase’ effect. See image below.
Also, when clicking Market (during battle) it acts like I am clicking Bouncy Disk instead… and nothing else happens.

In any case, this was a half-decent way to kill some time while waiting for some idle games in another tab, but ultimately there isn’t enough appeal for me to consider purchasing. That said, good work and I hope you find success.
