Demo updated, polished and re-released

Time for the final and updated demo to reflect some of the changes the game went through during this last year:

- Things that didn't work properly now do (no more falling through walls I hope);

- Things that did work, but were a bit meh should look & fell better (lots of new particles, sparks, blood effects and such);

- Lots of abilities to be unlocked that substantially change the moves at your disposal and the way you play; 

- Brazilian Portuguese and Simplified Chinese added;

- Recovery mechanic now can be used during levels when the boss is onscreen: hold B button or D key to stop and take a deep breath (and remember to release it before something hits you);

Can't wait for the final game to be released on April, with its 10 levels of chaotic blood collection. For now, these 3 should give a good idea of what it's about.
