Stuff I noticed
1) See image for the quest, i dunno what it's supposed to do given that the tower passage is blocked after you complete it. 
2) A lot of the maps seem kinda empty, in particular most of the road passages, the stinger swamp, some of the location after you exit Feylora's cave. There's oftentimes trees in a straight line and not too much variety, maybe something could be done to add flair to the locations. I liked the lunar shrine, the cave, some of the mountain pass to the tower, but still.
3) The balancing becomes a bit off starting in the solar/lunar shrines, for example the knight or the armored enemies are oftentimes not worth facing because you can just have half your health gone. While the rest of the maps before that are pretty balanced especially with the gold and gear you get. Maybe reduce the damage a bit.
3.5) The bosses are a difficulty spike but it's normal for the second boss in the dungeon where if you kill the enemies she isn't too bad, so are the ogres, but Silvaris is slightly bullshit because he can just spam kill one of you or deal ~80% of your damage. So nerf his damage by just a bit. And while i'm aware of the solar/lunar gear, see the next point:
4) The solar/lunar gear doesn't exactly offer you much advantage except against solar/lunar enemies which are only 1 section of the game. On the contrary they cost upwards of 8k gold which is ridiculous, I decided to just dump my gold into anything but.
5) The skills seem to have overall decent damage and usage, but Scything Rend which is an all enemy attack deals absolutely miniscule damage for it's cost. I appreciate the lack of all-enemy attacks for now because in some RPGs provided you have the levels and mana you can just spam those to grind, but the damage Scything Rend does doesn't justify the cost. Which isn't very applicable to the rest of the skills they seem decent
Not sure if I have any other immediate complaints, the story is decent, some of the maps look pretty good, for the most part there is decent balance for your gear/skills, but I hope you can take what I saw into account. Could work out
