Don't let the RPGMaker tag fool you, this is actually a fantastic game, reminiscent of the best JRPGs of the classic 16- and 32-bit era. The ensemble cast is fun and memorable, with each party member complementing each others quite nicely with their unique abilities. Too often in such games you will find a slew of useless abilities, status effects and debuffs that don't work (or that are nowhere near as useful as just dealing damage, for instance), but in this game, you have to really utilize each party member wisely to win, at least if you play on Hard (highly recommended for the best experience, though you will need an optimized party for the last boss). To the dev's credits, I don't think I found a single ability that was useless, and that's pretty much unheard of in the genre. ^^
There are no random battles; enemies appear on the screen, and they do not respawn. This is a godsend, because if there's one thing I don't miss from old jRPGs it's random battles every two steps that constantly interrupt your exploration. Each battle is fairly meaningful (again, on Hard) with plenty of strategy. Dungeon design could have been a bit more imaginative, it's mostly just standard "flip this switch to open this path"; but at least there's rewarding exploration and that's good enough. I would suggest to the devs to add more meaningful puzzles (à la Golden Sun or Wild ARMs) in a future game, that'd turn your game from good to spectacular. ^^
The story is nothing too original but it's well-written and engaging, never once did I groan in dismay at silly plot twists or anything like that, which happens far too often in these types of games, so congrats on a job well done.
Oh and what are RPGs without good soundtracks and art direction? Skyborn's is excellent in both cases, so don't worry about that. I really loved the sprites and characters portraits, the artists are clearly very talented.
I do have some mild criticism, but it's nothing that detracted from my enjoyment: the dungeons could have been even better, as I mentioned before, and the crafting system is a bit tacked on, IMO, and not all that useful. And when shopping for equipment, there should be a better UI to compare with what you have equipped (and of course offer to auto-equip after buying). Luckily, the menus are quick and snappy so it's not much of an issue to navigate between menus, but that could certainly have been improved upon.
Some have complained that the game is too short, but I disagree. Doing all the optional content I could find and retrying the last boss a few times, I have about 19 hours; that's more than fair for a game without filler. Personally I prefer this over a 50 hour long game with tons of boring side-quests and meandering stories that drag on and on, so I have no problem with the game's length. YMMV. I suspect those who spent less than 10 hours probably played on Normal or Easy and breezed through without doing the side-stuff, which is weird to me.
All in all, I was pleasantly surprised by how good this game was. I hesitated a long time before buying it, expecting a decent but probably amateurish product, but it's actually very well made, very polished, and the combat is, without hyperbole, among the best I've seen in turn-based JRPGs.
