Super game concept, puzzle, shooting...
The Space Pig is also very well animated.
As already mentioned, sound effects and background music would top it all off.
For jam sound effect you can use LabChirp.
Thanks, we appreciate it :)Oh I didn't know about labchirp, good one!
Never heard of LabChirp, but it's a great little tool. I might just use this instead of as3sfxr... or maybe just keep both in my repertoire.
