You warm my heart with your words! That is very useful feedback, specially today :)
The UI was very lacking (most feedback was about that)... the truth is that I had to do it in a rush as it was a busy weekend with other stuff, but I had some time today to do a cleaner version (plus i added a very important item in a fresh last level, image below).
And for the Mobile build, I was thinking on that, even for the jam release, but you know how time flies. As soon as I have time to add levels and a classic level selector, I will do an android release.
Thanks again, it is always good to cross you in here :D
