This was adorable. I want a glitcholotl or whatever he is. I also had an invisibility bug on the last level, where I disappeared unless I was jumping. But bugginess kinda fits the game - I assumed it was intentional :D
Only critique: I made it to the end of a level (I think it was the Win 95 one?) only to realize that I missed something and had to drop all the way down. It'd be nice to have a glitch counter so you know how many you're missing.
