The resolution issue was something I had no idea about, so I will at least give you leeway on that. Also, the default assets being limited in map decoration is something I can also give leeway too. My apologies.
The problem here is that Felm one shots more than just the bandits. He can kill a lot of enemies with one attack. Believe me, I am using Arestol often and is already seeing the effects of his growing strength. Selten is just ridiculous. I like caviler units, but he should not be able to take on an entire army alone without being promoted. Horseman knights are good, but not untouchable.
Sadly I never played FF Tactics so I will not be able to make a case for it, but that does not mean you should neglect taking the time in refining your games' balancing when it clearly need some tweaks to be made.
Since this is more of a slight parody of FE plots then I can take it less seriously. I was conflicted on whether I should take it lightly or I should take is seriously, so I am glad that cleared things up a bit more for me. Also, we do not speak of FE fates. Unlike your game, their plot was horrendously flawed and tried to take itself too seriously which makes it increasingly painful to sit through (also, Felm is far superior to Corrin as a protagonist). I am unfamiliar of how any of your games work, in terms of plot, so I would not know.
I do not mind side quests, but I try to avoid doing all of them just so I can get the optimal challenge from the campaigns' battles.
I am so used to dealing with a very serious and relatively grounded plot in SRPG's that I forgot that parody plots can coexist as well, so it was a bit of an eye opener.
In short, this opened my eyes to a few new things about your game and I do appreciate your reply. This still does not change the fact that a few fixes should be made, not mandatory but something I highly urge.
Hopefully, I do not sound like an elitist pushing my opinions down your throat. I just really care for your game and want it to be refined and enjoyable as it can be.
