First game?
WOW! This is pretty good for your first game. I like how it pauses if you click off the screen.
Some things I felt could be better: (note that I don't program games so I can't help you there, sorry)
--When you touch the raining swords (nice use of an episode btw), maybe there could be an animation that they "died" (like how Mario kinda jumps up then back down out of the screen).
- I agree with spencerthehuff, the raining swords are bit too much, but I also agree with dangerdino, if you could have less swords rain down, I don't think it would be that much of a problem. And if you
could include enemies, that could be cool, although I don't know what kind of basic enemy you'd have (perhaps you could have like the basic goblin or like those zombie candy-people, or you could create your own enemies too).
- Again, what dangerdino noticed is kinda important. Tone down the more high-quality backgrounds, make Finn and Jake more HQ bit-ish, or kinda mix it together or something (sorry about my bad terms, I'm not good at correctly labeling stuff...).
That aside, again, this is pretty good, and I hope to see another one later in life! (and I'm sure it will be better!)
