I'm surprised no one has commented on this game! This game is quite cool!! This game was interesting to play, and the added context and story was great. However, this game can be cheesed (or at least I think so), by not placing the magnet drone and dragging the package to the next screen, but It felt correct anyways. This is honestly a cool mix of tower defense and puzzle game in my opinion, with having to plan how to deal with the drones whilst dragging the package drone over. However, the game has a strange difficulty curve by level 9, with the combo of the saw drones and backwards wind, makes it really hard. tried a couple times, haven't beat it. Overall, this game is a quite enjoyable experience, with decently fun mechanics, although the difficulty curve is a bit strange. Nice Work!
(Edit: I've gotten to level 9 about ~5 times, and still haven't beat it. I'm not sure what I'm doing wrong :\ )
