Spent a little bit more time with other demos.
Tesla Force - Just like the previous game, a very fun twin stick shooter. Some gameplay mechanics have changed, but otherwise more or less the same stuff. Good times.
Haven - A french interpretation of a jrpg. A couple is stranded on a weird planet. There is a lot of silly relationship stuff, but you can switch between both characters. Turn based fights and loads of gliding around the surface of the planet. Production-wise, looks like one of the most accomplished projects in this demo showcase.
Galacide - Galaga meets Candy Crush. I'm kidding a bit with that comparison, but you will know what I mean when you play it. Looks fine, but not really interesting.
The Vale - A game blind people can play. Puts you in the role of a blind person and you have to do stuff based on sound. Probably only playable on earphones.
I think I'm done with the demos. It was fun to try some of them out, but doubt I will play the full versions of them. Maybe Hellpoint, Nine Witches, Raji, Tesla Force and 9 Monkeys of Shaolin when they hit GP.
