There is an obvious improvement in graphical fidelity over OiaL (especially for the MC, who looks like a human being rather than a high-functioning coke addict, lol), and the comedy is still here, but this hasn't hooked me as immediately as OiaL did. This could be because of the bugs on mobile (see below), it could be that the longer story has a longer spin-up, it could be that I don't find any of the characters particularly attractive yet, or it could be all 3. I'm not sure. Still can't wait to see what comes next, though.
A couple of things I can address directly:
-The 'hot girl' in the popular group looks like a background character from a no-budget Korean drama. I'm assuming it's because no time was spent on her character model as she is just a background character, but suspension of disbelief is difficult when there's at least 3 women in the class that are way more attractive than her. And at least one of those (Dalia) would be popular herself just for the fact that she's hot and athletic and not rough around the edges like Alex.
-At the end of the .1 story you're hunting the seventh gem, but earlier that day the AI said only 5 had been found, then almost immediately after the CEO announced the 6th had been found. The story seems to imply the "7th" had been in possession of these two for quite a while, so something doesn't add up.
-Blush is applied way too heavily pretty frequently, and is really distracting. It was there in OiaL too, but it was a lot less in-your-face. You could interpret it as makeup in that game, but in Eternum it reads as these girls are constantly embarrassed or horny.
Mobile Bugs:
text/character names don't line up with the text box AT ALL
the rapid scene transitions completely break and just turn black
it takes FOREVER to switch back to the paths screen after tapping one of the girl's pictures, but only the first time after opening the paths screen. Once it finally switches back, it's all perfectly responsive until you close the paths screen and open it again
tl;dr is Eternum is a huge upgrade over OiaL graphically, and shows glimmers of the brilliance OiaL had, but isn't there yet. But this is still version .1, just the tip of the iceberg, so I have high hopes.
