This is so simple and cool OwO
1. I'm a big fan of pixel art and minimalism - such a bingo here
2. Ez mode for noobs (like me) and hard mode for advanced players - great idea
3. This game is just fun and chill (unless you start an advanced mode lolol)
4. The less is more - it makes sense here
A friendly recommendation: ^^
I (as a fan of narrative design) would recommend you to apply some story here. Who is this tiny dude? Why does he give parcels? What is this world? What is the challenge for him? And so on. I'm sure it will make ur game much richer :D
