I'm not sure if this counts as a bug/oversight but is it intentional for units like Fire Mage to sometimes be referred to as firemage? I'm referring to inconsistent capitalization and spacing. It only struck me as aesthetically a little off when I caught it after battling or when I went to talk with the units at the hut.
I'm only a little ways in (around the Forest Maze) but I've really enjoyed it so far! It gave me a lot of early GBA Fire Emblem vibes with the character interactions and when I had the option to talk with the units in the hut I felt a wave of nostalgia. Also when exploring it reminded me of when I first played Etrian Odyssey on the DS, and brought back a lot of good memories. I've played a fair share of VNs and some of those hero collecting games, and I honestly think you've done an amazing job pulling out some of the best parts of both with this. The art, sound effects, and music also all fit together really well and its impressive how much work you've put into this!
I came across your page while looking for some inspiration in trying out Ren'Py on Youtube, and found your videos to be not only well thought out and educational but also honest about the pros/cons of solo development. Just wanted to say thanks for putting all your content out on Youtube (I know that also takes quite a bit of work!) and with your games themselves here! I look forward checking out more of your games and hope you'll continue making things you enjoy!
