I think I have solved this! Thank you for pointing it out
Happy to help, I look forward to the next release. Oh I had a fun idea for Endless Mode if you're looking for suggestions. Maybe a Bimbo penalty option, where every failed potion increases the shop keeper's breast size, and at a certain size they become bimbo'd. (And maybe each correct potion decreases the size, or something else?)
Some issues I found with Endless mode: Every time you start a new run, my default walking speed is set to max and the Wait for click Mirror option resets to the off setting.
Another big option is the Mirror continue button is a bit broken. See image:
The red highlighted area is the area you have to click to Continue. The blue highlighted area will not Continue. This issue is only in the Endless version, the normal story mode seems fine.
