The games was pretty solid for being a demo, but I found some things that bugged me, first was that the lag increases when you progress further into the game, secondly I thought the boss' health bar is unnecessary until the actually boss fight, and lastly, it would be nice to have a pause option rather than going to the main screen and having to start over by the checkpoint, hope you guys fix this in the newer versions, and good job on the game,

(It would be pretty cool if you could add a enemy encyclopedia or something.)
