Hahaha I was looking for some CC Synthwave song and this was the only I found, I have to speak with a musician friend to make something unique for the game xD

Well if you want a pretty cool website with a lot of free song, go check https://incompetech.filmmusic.io, I discovered it during the jam and they have quite a lot of content (you have to credit the website and the song in your project but beyond this you can use anything for free).
