Having loved Genetos for its unique gameplay and new ideas, I figured I'd post on the author's BBS and try to get an update on the status of his project. Luckily, Tatsuya Koyama can read English, and here is his response:

"Don't worry, I have still been going on to develop GENETOS.But, it's going to take time. I will put GENETOS's information on my diary.Please wait for it's update patiently.

I am going to release full version of GENETOS without cost.All my works are always FREE."

So the full version is coming, and all his works are freeware. Great news!!!!
