New Doujin Dump: Stein (2-player puzzle game)

[skpstmgs]

Here's a new doujin dump for everyone called "Stein". It was a Takeru release so no real packaging as you can see in the attached image.
It looks like a 2-player hot-seat puzzle game where you try to knock off as many of the opposing color's blocks in each turn. I'm not too sure of the rules as I only played a bit but someone might find it interesting.
Mouse is required - I don't think you can use a controller/keyboard for this.
When the game starts, there are a few prompts:
First prompt asks which game data to load. Default is "mendata", so if you hit enter, it will just load that. I noticed there are a few other files on the disk you can load like "kawamura", "hoen", and "nori". So you would type one of those names in the first prompt and hit Enter to load the different sets of stages.
Second prompt is the number of rounds: 1,3, or 5.
Third prompt is number of seconds per turn: 10-60.
Fourth prompt is self-explanatory, you just choose a level. 1-20.

Since I'm at it, I also attached a digital magazine called "Degital Magazine Vol.1" and a CG collection called "Ultra Fight". No games in those two, but maybe someone here collects them.

Enjoy!

I was wondering what stein was as there was 0 info on it and the pics on the auction didn't help at all hah. Thanks!!
