Story:
I came in expecting trope-filled flat characters which was true, but honestly the character development was way better than expected. Dialogue in other indie strategy games is sometimes so bad that it turns me away from the otherwise fine game-play.
In OAG, I actually read most of the dialogue and even some of the side stories. There was a solid main story and genuinely well-written moments between characters. Charming art style reminds me of old browser RPGs like Battleon.

I expected maybe 2-3 more story missions after the ending which felt abrupt, but good pacing overall.

Game-play:
Pretty simple game-play loop (go on 5 quest variants of a few different randomly generated maps, with about 10-20 different enemy groups each) with very satisfying character progression for anyone who likes FFT or Fire Emblem.
I got addicted to the grind and finished iron man hard mode in 2 weeks.

The combat is not hard, but I needed to play a little safe to not lose important characters. There's no penalty for passing days, but I needed to build at least 3-4 teams worth of units to make it through mid-game without passing a lot of days. You can grind as much as you want, but I tried to do the minimum to clear each story mission. Also there's not much advantage to changing your characters if you already found a few with good traits, because they can accumulate a decent amount of stats and passives that new recruits won't have.

Most weapons of the same tier felt the same but there was some good variation in armor and accessories. In the end it wasn't really worth grinding for specific gear for character builds.

Pacing was generally good but the mid-game (when encounters started to have many enemies, but before my units gained access to AOE damage or chain-kill effects) felt very slow and grindy. Even at 3x combat animation speed, I felt myself wishing for fights to be over faster. It got to the point where I actively avoided long combat missions in favor of exploration or boss missions where I could get away with only 1-3 fights, until my characters got way better at clearing mobs.

9/10 Impressive first game from a solo dev. They made great use of resources/assets to maximize the game-play loop without having it get too repetitive, with a solid story to go along with it.

Great playability, intuitive interfaces, interesting story lines.

Its a great game. My grandma says i can only play games if they're great. I love my grandma.
