Aaand, done! Just played through, then 100%d, the whole game (so far!) and I really enjoyed it!! The story was compelling and kept me engaged through the repetitions of the loop! Although starting out did get a bit tedious, admittedly. Spoilers ahead!
Santorini's explosive event occurring at just under 22 minutes makes me wonder if it's a deliberate reference to a certain other sci-fi time loop game that features a comparable event at around the 22 minute mark in the loop; are you familiar with Outer Wilds?
(This game gave me certain Outer Wilds vibes, although obviously it's very different, the time loop gameplay where you start each loop formulating a plan to follow up on what you learned previously is similarly engaging, which is high praise!)
The music in Astrape doesn't play when you're on the roof, which gives the amusing impression that it is actually blasting on the speakers inside the building :p (also the music overall in this game is really good, especially Astrape's theme! I wish I could download it for my playlist somewhere!) One note I do have is that the red text in action descriptions is pretty low-contrast against the grey background of action descriptions. It was just a little bit straining on my eyes to read. You might want to pick a darker red text? There are contrast calculators online that can help you with this :) Can't wait to uncover the mysteries of Strabo, Hippocrates, and Pneuma when they release! Wishlisted on Steam and I'll be sure to buy it when it comes out there, too! Is there any way I can be notified of updates here on itch?
