ugh terrible, this was not a joyful experience. only reason i played this "game" a.k.a. work simulator, is to complete quest. not sure... should i be mad at the game creator, whoever decided it belonged on a quest badge, or myself? ... the answer is D: all of the above
easy, to make it easier just replay level 21 a bunch to get upgrades maxed real quick (or any early level with tons of gifts). Hardly any strategy to this, most level can be beaten by one quick random click
was awesome game, the first few trys i got destroyed, once i got past the 4 or 5th level i didnt lose. first started with the first 2 weapons then added the push back one on all elevators, new elevators i skipped the 1st weapon and went right to rockets. so i eventually swapped all 1st weapon for rockets. 1st weapon and machine gun never went above upgrade 3. upgraded push backs first to 2, then after 1 level had enough to replace all machine guns with lasers. then upped all rockets to 2 then lasers to 2. Dominated this game. was quite fun. make sure ur shooting on the weakest floor and switch floors if needed.
