The game seems pretty nice, but moves extremely fast. I can't easily see the temperature range of the customers I have as the numbers connected to them are small, and I can't seem to put them down once I have them, which since I can't activate more saunas when I have a customer means if they're full, I can only let the queue pile up. And once the queue is open, I can't seem to close it again. So with new people joining the cue every two seconds or so, even with using the sprint feature constantly, I still end up with the cue filled before I can even finish with a second customer. That being said, I do love the music and the graphics you made, it's just the text for instructions and numbers are too small at times, covered up at others, and the font is sometimes hard to read on its own with all the curls.
I know the multiuse is the coins being able to buy multiple things, but it's something I just will need to take your word on since I seem to only be able to buy new saunas for now and can't get far enough to see anything more.
