Alright. Since I’m joining the Jam, I’ll finish the game tomorrow (I’ll still make new levels today, but most of the coding seems too be done). Tomorrow I’ll compose some music, as well as see what I’ll do for sound effects. After that comes the polishing…
The menu looks like the picture below, and you can see the full (simple) animation for it by clicking this.

I won’t upload a playable beta (Be patient [if you exist], I’ll be done pretty soon :D).
However, I already have an old (yesterday…) playable alpha!
There are more instructions and additional info for those who are interested, when you’ve pressed the links 
Thanks, and good luck (or have fun, if you’re just here to play XD)!
