Honestly a great game. Loved the achievements still haven't gotten them all btw.
The voice acting of Mr. Utah really made the experience of transitioning levels fun.
Music fit the game well just needed to vary every now. Nothing big of course but a simple change of tempo or octave would do. I ran into a few glitches every now and then but after a quick refresh of the page my second run through was flawless.
Hope you guys bring Joe back from the sun for a sequel.
