Saw the gdrive link posted by the developer on the Steam forums.
This epub was produced by Adobe InDesign and uses lots of CSS instructions for absolute positioning. For instance, a single-line paragraph looks like this
Code:
<p class="Body-small ParaOverride-1"><span id="_idTextSpan118" class="CharOverride-3" style="position:absolute;top:2760px;left:0px;letter-spacing:0.52px;">Cover: </span><span id="_idTextSpan119" class="Italic CharOverride-5" style="position:absolute;top:2760px;left:569.04px;text-rendering:optimizeLegibility;">The </span><span id="_idTextSpan120" class="Italic CharOverride-5" style="position:absolute;top:2760px;left:896.78px;letter-spacing:0.47px;">Demon </span><span id="_idTextSpan121" class="Italic CharOverride-5" style="position:absolute;top:2760px;left:1511.8px;">Lord </span><span id="_idTextSpan122" class="Italic CharOverride-5" style="position:absolute;top:2760px;left:1927.89px;letter-spacing:-1.4px;">Vazarath</span><span id="_idTextSpan123" class="CharOverride-3" style="position:absolute;top:2760px;left:2663.95px;">, </span><span id="_idTextSpan124" class="CharOverride-3" style="position:absolute;top:2760px;left:2751.92px;">by </span><span id="_idTextSpan125" class="CharOverride-3" style="position:absolute;top:2760px;left:2983.52px;letter-spacing:0.51px;">Denis </span><span id="_idTextSpan126" class="CharOverride-3" style="position:absolute;top:2760px;left:3487.57px;letter-spacing:1.19px;">Loubet.</span></p>
Just hitting "check book" in the calibre editor made it silently crash, smh.
I suggest they rebuild the epub in inDesign "exporting the book as a reflowable epub"/

It may not look pixel-perfect but will be much more workable for e-readers.
EDIT: iBooks and desktop-based readers (
https://readium.org/about/applications.html/ e.g.
https://github.com/edrlab/thorium-re...eleases/latest) are able to view those fixed-layout epubs (FXL or FLO).
Inkpads being based on Blink/Chromium, it would definitively be possible, but not at the moment.
