Floppy snoot for more kinetic energy!

That face looks like it fit better on Kyubimon, but interesting choice. Also rare to see some Knuckles.

Bloopers: Portals disappear again. Oopsie-daisy!

It was only after the very long intro had finished, that I discovered two things:
- there was a way to skip it
- there is actually a decent game behind it

You have several options to improve this:
1. make a big button on the intro screen that says "SKIP INTRO"
2. have the intro be optional (replace it with the "quit game" button that basically does nothing useful)
3. shorten the intro significantly

The game reminds me of Commander Keen / Duke Nukem.
The story there was basically "there is bad guys, you is good guy, go shoot 'em"

Absolutely no need for so much heavy handed fluff. It takes away from the experience.
