Jetpack Joyride CSE2 Edition

Downloading...

You need a powerful device for this to run at full speed.

I put Jetpack Joyride (or something resembling it) inside Cave Story. It still needs quite a bit of work, but it should... play like Jetpack Joyride. Select the "Jetpack" option from the main menu to play.

If you want the offline version, you can find it
here.
If want to do this with your own mods, please see
this post.
