The description also says that they aren't sure if the game will be finished, so make what you will of that.
But, on to my personal analysis! First and foremost, I'm going to start with flaws since there are very little of them. UI is choppy, jesus, it's not smooth in the slightest. I don't know it just seems stiff whenever you move the cursor, heck, I think FE1 had a better cursor speed. Granted, the slow UI and such are probably because of SRPG Studio itself, but it's still unnerving to see. View of the maps seems a little bit too far for my taste, but other people might enjoy it. Animations do need some work, but the game is only 10% complete, so I'll let that slide.
On to the good! Map design is good so far! I really like Chapter 3's composition. A lot of different chokepoints and a heavy amount of incentive to make it to the villages on the other side of the map. Though, I'm not a fan of having a random gate leading up to the hill, lol. Levels seem to be a lot higher than a regular FE, Not!Navarre joins at Level 5 in Chapter 2, plus you have two units at the beginning of the game at Level 6 and Level 7. So, no traditional Jeigan/Oifay it seems like, but to compensate for that you get two higher level units. SOLDIERS, HOLY CRAP. SOLDIERS. Music is very catchy and just great overall. Except, the music might be SRPG Studio's premade ones, still doesn't detract from the fact that they're cool. Also, I swear I saw TearRing Saga portraits, the unused ones at least. If that's the case, pretty cool that Kaga found a use for them. To comment more on the art, this is full on 90's style, Kaga must really loves the 90's. I've read that some older calculations are making it back, so better stack up some luck if you don't want to get critted. Overall, this game looks like a Fire Emblem through and through.
Also, the brother name is Zechs. Uhh... I guess I'll make Gundam jokes about him.
The choppiness is definitely noticeable, although I'm not sure if it's the recording program they used which records it at a low fps as the battle sprites feel like they're not animated as smoothly as the should be, granted it could be them using the standard/default sprites that come with the engine, considering they're only 10% done most sprites are probably placeholders.
On the subject of levels, it depends on from game to game, coincidentally I'm currently playing through FE12 and Marth starts of at level 6 in that game, to give an example. Hopefully the levelling curve of the enemies will be right, don't want another case of Sacred Stones where every enemy is just plain outclassed by your units.
Also yes playable soldiers, why is this only a thing in FE9 and 10, considering every FE ROM hack in existence has them you'd think they'd get the hint of how popular they are.
Yup, those are TRS beta portraits that didn't get into that game (some might also be from berwick saga).
Also crit multiplier is 2 instead of 3, which I really like as the 3x multiplier tends to help the enemy in my experience.
I don't know what to put here, not allowed to post gifs, not even by putting it in a spoiler, so have some empty space:
...yay...?
