My first day: a lot of stuff to do. The game seems enjoyable.
Although i have issue to grind: i leave browser open to idle and it crash/freeze, sometimes even while active play with clicks, sometimes during upgrades.
Upgrade resources can be really confusing when begin, i would add hint/tip in the upgrade section to have an idea where to looking for.
Champion to legendary mutation is trivial. If you have champion, you actually have the legendary too, there is no chance to mistakes, just random gym/feed them (if you don't look at the mutation guide). Common suggestion would be more beasts: like a champion can mutate in two forms. Or if you are not ready to add more beasts, you can cross the mutation: for example if you mistake carac, you get thundaga, or if you mistake sydra, you get syngard.
This game is a joke.
You can buy elevators every 2 floors, do it, price will double from 1k to 32k.
Begin by equipping every elevators with turret x3, keep in mind the price of new elevator every 2 floors.
Then change turret step by step when you can afford: rocket laucher + turret x2, rocket launcher + machine gun + turret, rocket laucher + machine gun + laser.
No need to upgrade nothing, last setup can handle every floors even for lvl 1. I upgraded 1 elevator to almost max just for the sake, but lvl 1 is enough.
The guy is useless, just press fight, go afk and come back in few minutes...
Summon skeleton is a good way to manage multiple enemies, your skeleton get aggroed, but you need to step back few corner to decrease the amount of enemies and face them one by one.
