I was wondering when someone was gonna mention that elephant in the room.
Regardless, onto the game. I'm having issue trying the demo from the dlsite. It asks me to choose a resolution, then the main title appears. I press one of the arrow keys, and the game crashes.
edit: Alright, I seemed to have gotten it to work by troubleshooting it. From what I've played, it's pretty fun, and the scenes are well animated. Though it's weird some of the animations from the one enemy in the game are unavailable, along with the other enemy. I really hope that the game is not just 15 bucks for one more enemy and the rest of the animations for the first enemy in the demo.
