Tiptushi was pressing you back hard taking ground on multiple fronts and with fast attacks. But eventho he did a lot more scouting then you did he missed your base.
You broke his attack and economy completly with that first t2 naval sneak attack. One breath short of killing him, but that made the game only better.
Thx to both players this is one of the best combined navy / air / transport replays I have seen so far
