Good job
This is a good game. My only complaint is that to fully appreciate the game, you must a) increase your resolution (as newgrounds has the incredibly annoying habit of being a nuisance and not letting you scroll when viewing a game, and it won't fit and b)figure out through a long trial-and-error what the heck the difference between general and specific upgrade is. That is all, either way, this is a good beginning step up to your Unknown: Portector's game.
