Dungeon Knight

The game itself loop is okay, it doesn't really do anything innovative but it works, but the big problem the game has is that it relies extremely heavily on the premium currency to do anything in the game. That wouldn't be too much of an issue as the game allows free players to earn premium currency except... I've only ever managed to get an ad to work once—ever. And it didn't even give me my currency. Any other time, all I've gotten is "no ads available", so when ads don't work or load, a free-to-play player basically has no way to progress in this game because the game relies so heavily on the "diamond" currency to progress. There two ways to fix this: One— try to load the ad, and if it fails, give the player the currency anyway since it's not their fault that nothing loads or is available, or two, balance the gameplay loop so diamonds aren't SO important that they are basically a requirement to progress through the game by giving you extremely high multipliers (also fixing the ads so they actually work would probably be a good idea, too). If the simple gameplay loop of your game wilts for free-to-play players because something as simple as ads not working, than it may be time to rethink the current game design balance and how much "support" you may be 'asking' from your players.

Meh. At a very early world stage you hit a pay wall in a way that no matter how much you upgrade and get ad-provided buffs, you still won't be able to progress unless you spend a s***-ton of real money to buy gold to use for upgrading. Just another get-rich quick schemes that plagues today's game developers. Not to mention it eats ups your battery fast meaning there's something going on in the background that we don't know about. Probably mining crypto currency. I don't recommend to download.

The idea is decent, but the gameplay just doesn't go anywhere. Same generic levels and you arbitrarily upgrade stats. That lets you progress to further levels with the same enemies, skills, etc. It's a grind fest with no noticeable payoff. Oh and Arena? Don't bother trying it. You get matched with people who are 10-50x stronger than you. There is no actual calculations to their matchmaking system.
