Wow! The animations in the intro put me in a relaxed mood, and I liked that a lot. I'm amazed by the art! The player movement feels good. I appreciate the way "A" appears when I walk near clickable objects. The sound effects all fit really well! Love the humour. Made me laugh out loud several times. :) :)
On the calendar, I didn't actually notice the day being crossed off at first. I think my eye was instead drawn to the "A" at bottom right. Could day 1 perhaps be the 9th, and move the "A" to the left of that calendar digit, so the "A" is near to the animation?
Brushing my teeth... I had to open the crank... the system sound that occurs is very cheerful and I felt broke the mood a bit. If you are using Lua, looks like playdate.setCrankSoundsDisabled(true) (untested) would prevent this?
At one point, I thought I was opening the fridge and was puzzled by needing to pay: thought I was in a shop. Looking back, actually I was leaving the house. Perhaps the "A" by the door could be a bit lower, away from the fridge?
I found some weirdness in the spreadsheet... I clicked both 19s, then changed my mind, clicked one of them again, and it didn't quite do what I expect. I can't remember the exact details, sorry - let me know if you need more and I'll happily go back and poke at it with a bit more care.
"ALSO can I get a vibe check, would you be interested in the full finished version of this?" Having played this prototype - yes, I would! (See first para.) But if I were coming to this cold... it's the ironic humour here that I really like, and I didn't twig that was here until I started playing.
