I noticed there a long day for the game to load. For me it's about 1 to 2 minutes. I heard others around 5.
During play I get an occasional Garbage Collection pause or at least that what it feels like.
The game is sooooo freaking hard.
If I may make one suggestion. I know that the period classes system is the only persistent element. But it would be great if leveling did offer a small persistent bonus too. But that's just me. Leveling feels of very little worth when there are some fab champion items.
Otherwise great game, well made. I'm glad to see such a well done game in C2. Gives more weight when talking to people that C2 is a good choice for 2D games :) you all rock at AWG
