This game feels like "Memento (Christopher Nolan film) x Exit 8." I NEVER thought in my life I'd get to experience this combination, yet here we are!!
I loved the concept of going back a day (great interpretation of Countdown, btw) so you could finish your pending tasks! With each passing day (in reverse, like Memento), a new narrative beat is revealed. Kept me intrigued until the "Inevitable" ;p
Also, great use of minimal space. I STRONGLY urge you to keep developing further. Very unique, and intriguing gameplay.
(p.s.: Stay hydrated XD)
