when i open the html5 link, i get a screen telling me to "insert cartridge"

just tried the postjam version. the screenshot in this page looks much more appealing to me than the actual postjam version. it took a while until i understood the concept, but then i realized that the game mechanic is actually a nice one

I like it, but it's too short.

ok the original version works in chromium... in firefox it didn't work!
i prefer the original version, it looks nicer and has sound

It took me a lot of time to understand what I had to do and what the controls were doing. I'm not sure if this is on purpose, I have there was a few explanations. Once I understood it was a quite interesting puzzle game, but way too short. Nice job anyway.
