Thanks for the feedback!
I was going to make the vibration an independent toggle (it can be toggled together with the sound with the mute button), but I may take it away entirely, since it gets annoying way too fast.
I’m currently polishing the prestige system and adding upgrades, so there’s no plan for an ending until at least I finish adding all of the basic features.
Regarding the the itch theme, I changed it recently and didn’t notice those issues. Thanks for pointing them out! I’ll look into it.
EDIT: I changed the itch theme back to the previous version and removed vibration entirely in the newest update. Again, thanks for the feedback!
