This is just amazing!
I love what you did with the level selector being a working version of a bunch of game machanics. Makes for a great experience and already works as some sort of unwritten tutorial for new players.
Even though game controls are simple they require some dexterity due to the cursor & peeps distance mechanic. Level design is just great and the start system + timer makes for great replayability.
The music fits great with the asthetics and gameplay. Sound effects and visual effects are great too. And I love the additions you've made to the art asset pack, they fit right in!!
Great work!
