The continue/resurrect option works only once, but can be bought multiple times. I understand why you don't like it and I like the perma-death aspect of the game a lot too. It's just that I'm experimenting with this whole IAP business and this is one of the ideas I had. Sometimes you just make a stupid choice and wish you could get a second chance. Also, I'd love to hear your ideas about IAP's or the game! I can't promise I'll add them in though, as I'm wrapping up the game for the Android release at the moment. But please do share 'em :)
Wow, 30 runs, that's a lot! Glad you like it! I've heard from many people that around the second boss it gets really hard, so I'm going to tune that down a bit there. Ideally, you'd finish the game after a couple of runs and in that way unlock a new character that's a bit harder to play. It should be challenging for sure, but not feel like it's impossible.
