The minimalistic style achieved here is something worth celebrating: It's incredibly polished! I love the palette and the sharp text elements.
When animating things like the text dropping and bouncing, along with the scene transitions, it might be worth adding some squash and stretch to objects to sell the motion, as well as some easing in and out to make the tweens look a bit more natural.
The gameplay of optimizing free and locked tasks lends itself to a pretty enticing meta-game, but Day 2 seems exceptionally more difficult to pull off when compared to 1. I'm curious to know how the tasks are chosen for a given day, as sometimes it felt like my day was riddled with locked tasks with high time requirements.
Regardless, this is great work! The sound effects in particular were very charming.
