Use consistent wording. Having things like construction, building, and carpentry all referring to the same thing in different places is a little confusing.
Another suggestion: dim recipes in your collection that you don't have the ingredients for (but don't make them inaccessible cuz you still need to see what ingredients you need).
Protip: Lots of people play turn-based games BECAUSE they don't have coordination-based gameplay skills. Don't make medals based on that. I mean, seriously, my high score on the freakin' dolphin game (#2) is 22 after five tries! The first time, I got 2. Yes, seriously, 2.
Well, it's a dumb but easy way to get the 50k...just skim across the top and do tailslides (up & down at the same time) for 2 minutes, and you can get the 50k easy. Other than that, I had ZERO skill at this game!
Level 11's just too freakin' hard to coordinate. The guy always gets on the elevator no matter how hard I try. Gave up at that point. Rating: 2 for making such a coordination-intensive level.
Too hard, no strategic form of play. Never been good at this sort of thing and didn't even finish Wave 1.
Designers: Ever heard of a "novice" mode? We're not all hardcore gamers!
Gods survival mode is boring. You get the right character combo and you can last forever with ease. After hitting 40, I stopped doing anything but basic attacks...when that still didn't get me killed, I started passing at the lvl 45 boss wave.
