This Game is Amazing, some constructive criticism for the dev though.
1 the buff skill intensity is a hugely busted skill. Pun intended. it easily gives enemies that use it a huge advantage against you early on, as they can grow far faster. And it is game breaking. the enemies easily have over 3000 buffs of all five types before you even have a chance to do anything.
2. the armor mechanic love the idea, but I have noticed that I am not leveling the fat stat because anymore and I break almost all my armor. maybe have the threshold for breakage increase by 20 a level instead? just an idea.
3. the concentration skill having multiple levels for use is a great idea that maybe should be used for other skill, the first level is 1 extra ap, I'd probably have it be at least two at first level so it's a little more worthwhile to use. also a glitch happens when multiple growth buffs affect you at the same time, it break all the future buffs. additionally it causes you to get those buffs when you leave the fight. another glitch happened where when I had a fight and instantly hit another fight it caused all the enemies to sink into the floor, only reason. I know is I saw their heads poking out of the ground.
Sorry for the word soup. just love what you've created and wanted to see you do well.
