Matt I love your games! I grabbed the older ones off of your personal website (that you have hosted) and greatly enjoyed EBF 3 (though mostly played it offline on my laptop). Do consider a 'bundle pack' of all your games all together for like $25 or something because collectors love that stuff! I know some of the older games are a bit of a pain to turn into self-contained EXE files but it can be done (I've actually done that already for my own personal use; it just embeds the flash file within a small SWF player).
Just stick a note that the games older than EBF3 aren't fully supported and let that be it. I hope that my Steam forum suggestion about native controller support for your games may become a reality sometime :)
EDIT: If it is possible to buy the game DRM-free here on itch and also get a Steam key with purchase that would be amazing! I have many friends who want to play via Steam (for achievements mainly) and I want to be able to also play it on Steam while having this itch.io version as well.
