Hey, I liked this, I like the idea of a long-form idler game for productivity. I think you succeed on making this.
I think this game really needs a timer beyond the animation on the coin icon, and it needs to pull through your goal from the other tab to the screen with the wizard/witch. I found also that I can cheat and set a goal which will take 555555 hours and then immediately set it completed to get a lot of coins and be able to buy everything in the store. I think maybe if the number of pomodoros it would take is longer than 7, it should prevent you from putting the goal in. I also don't think the break portion of the pomodoro is implemented?
I found some issues with moving the player character around, they would sit in the ground and also block the pickups.
There is a very good variety of things available in the store
