Yes, it's a 32bit app. You could try to find Wolfling on gamejolt, I think I have uploaded a 64bit/intel version of Wolfling over there some time ago. I would be happy for feedback if this version works for you...
I was able to get the 64bit version for Mac from Gamejolt. Thanks for the tip. Unfortunately it crashes on launch. I'll try it out on my Windows laptop. Thanks nonetheless.
