Hi there. I haven't had any glitching issues that I've noticed, but the function of the game itself needs to be redone.
1. This game is entirely inconsistent when it comes to enemies and their difficulty levels. A level might say Easy difficulty or may be green or might have a low number, but you can still get slaughtered even though you've easily beaten other levels of the exact same difficulty. Also, you might be in a dungeon where you are easily killing everything, and then some random single enemy shows up that is strong enough to wipe out your whole team. It's ridiclous!
2. There needs to be WAAAAY more money available! Each character has 4-5 items, and to buy new characters takes 10,000+, yet you might only get anywhere from 300-1,000 silver in a single dungeon. By the time I've bought maybe one new attack item for the 5 characters I have, or one (and only one) new defensive item per character (and that's defense OR offense, not both!), the game's difficulty level has changed, and the items have all gone up a level. There's just no way possible to keep up with the difficulty level unless you pay a bunch of money, which is basically cheating and renders the game pointless to play! And if you replay old levels you already beat, the reward is nearly useless! Rewards for each level and each difficulty should remain constant so that a party can level itself up and buy new gear when needed.
Summary: Make the difficulty levels and the monsters in them consistent, and provide the ability to earn enough money to actually pay for all the costs!
