So I spotted a potentially interesting new game on DLsite (not H).
The description says it's a physics-based puzzle sim. Sounds fun! But... what is it? There's no demo version. Of the three posted screenshots, one is just a title screen image, nothing to do with the gameplay. One is a picture of the back of the BOX (many doujin games sell at least a handful of box copies) with screenshots too small to make out gameplay details. Only the third lets you see anything about what the game looks like to play... and with so little information it would be a huge gamble to assume that it even RUNS on English windows, much less is comprehensible to people who can't read Japanese.
And for all that, it's got a highish price for a doujin title. Certainly not unreasonable, there are plenty of games on DLsite for $20, but it's not the STANDARD price. Most things are cheaper.
Unsurprisingly it's not selling any copies on the English side. (Okay, the majority of stuff doesn't sell on the English side, because, well, it's not in English. But still.)
... Of course, the next thing I click on is a downloadable set of speech bubbles. For $50. Good luck, you'll need it.
