Hello, thanks for playing the game and apologies for the late reply! Thank you for the feedback as well.
The game was designed around multiple playthroughs (a single run is about an hour long), so the player should learn the mechanics of the gam e as they try out different options over the span of several runs. I'm personally not a fan of in-game tutorials myself. That said, I'd consider putting in a short image manual for players to explain what the different parts of the interface represent. I am considering putting in non-combat segments between the battles too, since I have had a lot of people comment on how drawn-out the game feels--having something like that would definitely help with the feeling of being overwhelmed by the amount of battles.
The font issue seems to be caused both by not having the font installed and not having it in the folder; I'll have to include it in the next release of the game.
