Just finished Megami Tensei. I've actually enjoyed it quite a lot, even if Mazurka and Infini can feel really long and a bit boring at times. I did run into a glitch or two, but they were mostly related to the text being mispositioned or scrambled.
As you can see here, sometimes the game has problems with showing the names properly.
In the Cathedral of Shadows, demon names can get a bit messy at times.
This only happened once (or maybe twice), but the spell names have been completely shuffled.
Same as above, but this time with items.
Some text is mispositioned, but nothing major.
Overall, none of these glitches that I ran into hindered the experience in any way, but thought I would share what caught my eye.
Thank you so much for your hard work, you are a true hero in the eyes of many western SMT fans!
