As usual all of the mechanics are terrible and overcomplicated. Levels, stats, the way combat flows, etc.. I'd say something about amateur hour except honestly there's games made by theoretical professionals that play even worse, so... And, of course, in either case the designers always assume "No, it's not that I don't know what I'm doing, it's just that the players are dumb." Very possible, but if so you're the one making the game that only dumb people play. Maybe you're also dumb.
I'm just thinking about the "physical resistance" stat. The notion being that it lets you ignore certain status effects. Well, healing is easy enough in this game that unless the enemy one-shots you, HP damage alone probably isn't a threat. So either the enemy has to target resolve, which is basically an entirely separate minigame that has no connection to the hp game, or they have to use crippling status effects. If the player could actually increase physical resistance enough to matter, then it would shut off one entire way for enemies to be threatening. So you can't let the player get high enough physical resistance to do anything because it would upset the game balance. So you have an entire mechanic that can't be allowed to work as intended because it would break the game. Evasion or whatever you want to call it is another big one in video games. If the player could actually build their character in a way to reliably avoid being hit, then you don't have much of a game left. So you can't allow the player to ever raise their evasion high enough to matter. If the player can't rely on evasion to work, then why bother with it. You might as well have not put it in your game in the first place, except you think you're so clever and you don't want to admit that you didn't think that hard about it and you don't want to spend the time and energy it would take to actually build it out as a full-fledged thing, with perks and traits and items and enemies and weapons and spells that interact with it to give the player meaningful tactical decisions.
I'm sure it's very frustrating that your life's work is just a Flash game porn parody of Final Fantasy focused on furries and explicit descriptions of very strange oversized dicks, and you want to feel like "No, actually, it's a real video game, just look at all the numbers and rules and things I made up for it!" but you people (the devs) need to chill out. The relatively simplistic gameplay in the first Corruption of Champions was obviously good enough.
