Do you think if you can put a box counter as part of the map's HUD? I know we have one at the end of each level, but sometimes it can be irritating to backtrack to 100% complete a level.

For example: In Level 4 (from the ruins to the Egypt to the toxic levels) I thought i get every box in the level, but i mostly get between 135/140 - 138/140 boxes. Normally because it looked like i got every one in that level. Either that or i don't know where the rest were. But i think it should be fair if you add it as a minor update, if you can.
