Demo: didnt save, sorry 
THIS IS NOT A JUDGE RUN
THIS WAS TESTED WITH 4 TO TEST PACING AND BALANCING
Soldier
Engie
Scout
Pyro
wave 1
overall too easy, felt like normal at most, nothing threatening, map is very long and this wave will never push outside first rock, scout bots repeated for over a minute, champ subwave is useless and doesnt do much, this wave needs work
wave 2
very weak wave again, only pushforce was because giants have high hp, only consistent dmg dealers were conches, this needs a solid rework
wave 3
boring wave in general
no pushforce at all, fighting giant flares for 2 minutes isnt entertaining, first minigiant heavy sub will never push, they are too slow for sole bomb carriers
wave 4
wave was just hold m1 on tanks simulator, pretty boring, engie could solo entire main wave lonely
wave 5
wave suffers from no giants, only commons are spawning until tank arrives but then its still mega weak comparing to w1
wave 6
only somewhat threatening wave, still it didnt count how short the map is, that wave could work on decoy like map
wave 7
boss is very bland and uninteresting, melee soldier with absurd dmg bonus
Overall
Mission suffers from being on bigrock mainly, nothing will ever escape the cave even with 2-3 decent players, boss and tanks are build to have very uninteresting peace, mission pretty much needs a rewrite.
My tip would be to think about adding more subwaves onto the wave but not that many to make the wave last 5 minutes, add variety to waves, try to take an advantage of the map being this long, dont be scared to put a lot more pushforce than this, try to test as many times as possible with people before your next submission post.
