Great job with this! Very playable, really nice minimalist art style with lovely monochrome color palette, solid music and gameplay, playable in-browser, restart and tutorial built-in---this does pretty much everything right! For a first game, this is a knockout. Fantastic work.
There are few things to truly improve with this game, which again is very impressive for a first outing. Consider sprucing up the itch.io page, however. If you press "Edit theme" button in the upper-left corner, you can change the color palette and fonts of your game page, and upload screenshots and custom background art, etc. for the page!
Wonderful work, I hope you both continue making games!
