Congrats to Mega Crit Games and Slay the Spire: now with 3 characters, 3 modes, and 1 million copies sold. On sale for the Steam summer sale!
The 3rd mode is Custom, and it seems to subsume the daily challenge. I mean, you can still do the daily challenge, but custom mode gives you all those daily options, and more, and lets you pick from them. If you are not playing for the leaderboard, custom mode does everything you want and more.
Custom mode is what it sounds like: you can pick custom modifiers. That includes all the daily challenges, plus some that StS had recently added as special seeds, plus more to come. You can still set a seed. You can pick what character and ascension level you want. The original mode is still The Real Game, but this lets you play the game however you want.
So that’s pretty cool, even if it lets you completely upend the balance of the game (in several directions). There are a few kinks to work out, as you can select mutually exclusive modifiers. And achievements are also turned off, if that matters to you.
