A message log, pretty please?
 

The space bar pauses / unpauses the game, but it also closes pop-up messages. I must have closed close to 10 messages so far because of that fact. There's no way of knowing what the messages were once you've closed them, so some kind of a message log would be crucial to have.

that's the same problem I had too! The only keys we can use is space, ctrl, M, and F-keys, should that be relocated more closely, like the old game SudenStrike used the ASDFQWER keys, that would be even better~
