It took me a lot of time but I finally got an almost complete version of the game going. This should be really close to the finished version so I called a demo instead of early access ver1.3, technically is the same, but calling it demo makes its feel like I'm actually progresing.

Anyway, this version includes a lot of new gameplay improvements, added collectibles and the long awaited extra game modes, also rebalance the boss fights, by reducing the amount of health of the boss but decreasing the cooldown time  between attacks, the idea is to make the fights shorter but a little more intense.

Also created a HTML5 build of the game so you could play directly on your web browser without downloading anything, so now its free and fast, pretty great, right? Wel... the web version does have some minor visual and audio problems but nothing that substract from the experience.

Please give a go and tell me what you think, I'd like to iron out any problems before moving on with new content.
