I love the style, the idea is really good and the gameplay is fun, with a little bit of music it'll be great. The only "inconvinient" is that it's needed an emulator, it's not a bad thing but the page don't say that.
I’ve finally updated the game with some music!
If you only want to check out the music, here’s the music on my Bandcamp: https://eterdev.bandcamp.com/album/linkedout-ost
