That was good fun :) Very pretty art style and the boss in the top left was creepy haha! I had the same issue as the other poster and kept getting stuck on walls which made the jump pack sections a bit difficult.
One change I might recommend though is that I know the map is a Castlevania Symphony Of the Night styled one but it might be good to have the option of having a smaller map on screen to the side like with Metal Gear Solid 1 for example!
Either way though awesome entry! :)
