Well, for no discernible reason, the crashes stopped entirely after I posted.
I've beaten the first episode, and it was quite good, if a bit Nintendo Hard at times (the total inability to turn around even if you just jumped off flat ground a tenth of a second ago and are facing the wrong way; also all the time-based challenges, especially Cham's race for the ship charge, Polvere's toxic planet, and FRICKING GOLDSCHMIDT). I really liked the camera system and the device puzzles; with the exception of the programming one (FRICKING GOLDSCHMIDT) they were all very intuitive and didn't take too long to figure out, yet remained challenging. Space travel was similarly intuitive, I liked its additional features, and I only came close to missing one of the stars (FRICKING. GOLDSCHMIDT.).
Overall, I approve wholeheartedly of your work, and look forward to future installments, should you choose to make them. And I hope you do; I would like to get an explanation of what's going on in the world.
Until then, I'll be playing some of the other games here; after Saira, they look quite promising.
