Is this your artwork? If it is, it is very well made. It might have been a good thing I died because I got to experience the death sequence which I enjoyed (I know, strange right) but it was a cool animation and the voice acting adds to it. I forgot to change my refresh rate so I played it on the super difficult mode but it seemed okay enough. :P Didn't like those darn bats or whatever they are...they refused to die! :( 

Well done! Game was a lot of fun.  The enemy types were well executed and the A.I. was very well done.  I feel like with the enemy types you gave yourself all the tools needed to design some fun platforming but you probably could've done a little more with the actual level design to make it more fun.  Perhaps some tweaking post jam.  It was a lot of fun non-the less but I just feel like with the A.I. you've already built there is potential for a lot more.  The boss is definitely where this game shines and with the difficulty of the boss I think it was a wise choice to put a checkpoint just before the boss.  I think players would have lost patience quickly if there was lots of back tracking.  I was super impressed with alll the different boss cycles, and randomizing them was a nice touch.  Art was very nice and felt like it all fit together well in the game.  Also if you do any work on this game post jam I think this game absolutely screams for gamepad support. Solid work!
