Slay the Spire 12+

Short take: Quality title that is definitely worth owning on iOS. The port, which could have been better, has been stable and playable from day one. Buy it. You will probably find that you have fewer problems with it than you might expect.

Long take: Sticking with Humble—in the most favorable light—reflects poor judgment in terms of first choosing and then sticking with an incompetent service provider (ie, the porter in this instance). One- and two-person teams who have enjoyed, at best, a fraction of the success StS has enjoyed (across multiple platforms, by the way) have managed to produce and support card games—over the course of several years in many cases—that are much more polished on iOS. Exhibit A is Lost Portal CCG by indie dev Michael Camilli. Exhibit B is Pirates Outlaws by Fabled Game Limited. Other examples include Miracle Merchant and Card Crawl by indie dev Arnold Rauers. Image and Form, a larger studio, brought over a high-quality port of SteamWorld Quest. There are countless examples of the same on iOS. MegaCrit wet the bed here and chose to lay there instead of doing something about it. It's an embarrassment and iOS buyers deserve better. Keep in mind the fact that a number of iOS users have supported MC time and again by purchasing StS on multiple platforms. They expected the same quality on iOS that they experienced on Switch, PlayStation, etc. but got far worse.

This game is dangerously addictive in how much fun it is. My work productivity took a bit of a hit for a few days when I first got it. It has tremendous replayability as every time you play it will be different and you can play around a lot with how you play it. I have a few minor quibbles that would make it better.
1. It is too easy to accidentally select the wrong card when choosing one to upgrade, I’ve been scrolling through and accidentally selected a different one than I wanted repeatedly.
2. It is easy to accidentally play the wrong card as to read the full text you have to tap them to raise them up to full visibility. It’s very easy to accidentally play the card when doing so, although I suspect that it’s less of an issue playing it on a tablet rather than on the iPhone with the difference of screen sizes.
3. The last issue is more of an ask than a bug. I would love it if the game had the functionality to allow you to listen to music, podcasts, or audiobooks while playing. While the music and the sound effects are well done, I like to listen to other things while playing games on my phone and whenever I load StS it automatically stops whatever I’m listening to in favor of the game’s soundtracks.
Other than those issues, the game is super fun if you like deck builders and I recommend it without reservation, more than worth the cost.

Keeping away from five stars for now since the port has a few kinks to get knocked loose. The game itself is great, highly addicting and superb replay-ability (since it’s impossible to play the same game twice), and the majority (if not all) of the game has been refined to its best state. When the iOS port was announced and subsequently released I was ecstatic, and bought it immediately!

However, as it’s meant for smaller screens and played with fingers, the port needs, in my opinion, some QoL changes to help the UI feel more friendly. First, many of the options in both the main menu and in other locations with small text are too small to comfortably use, as misclicks are all too often. Second, as others have said before, the card selection mechanics are a bit wonky ; to elaborate, there are multiple times I select a card to read it’s use, but then wish to play a different card. Due to the selected card hovering around my card-hand area, it makes it difficult to select a new card to play (especially with cards that can be played just by placing them on the field; those have a tendency to be played instead of de-selecting). Besides this slight nuisances and the occasional sound glitch, the game is amazing performance-wise for a full PC-to-iOS port! Must buy!
