I just played through Pony Island and really enjoyed it. It doesn't have much replayability, but it's a unique experience that I think most will enjoy. If you like Doki Doki Literature Club, Undertale or Inscryption (last is the same dev), you'll like this.
I'm going to be picking up The Hex because I've liked the dev's other two games.
Wildermyth is a lovely combination of storytelling and xcom-style combat, with a genealogy system and chances for your heroes (and their descendants) to reappear in future games.
As others have said, prices should be mostly stable, especially for big names, but you still might see a few small devs who were like "Oh shit, its the summer sale, we should add a discount" halfway through.
