Thought I'd post that I find version 2.0 much more playable than 1 (I only had the demo of 1, but bought 2 after trying the demo).
After playing the PC version for close to 10 years (half demo, half full version), I found it tricky coming to the iPhone. The thing about Slay is it's all on the screen, and it's "quick" to play. The iPhone was much trickier to interact with.
For some reason, I've found 2.0 heaps easier???
So, some positive to take out of all the negative feedback of late!!!??

Glad you're still at it! After all this time, Slay is still the game I come back to time after time.
