Hello! I think I've found a game ending bug T-T After talking to all of the villagers, I've gone back to Madame Reytok, and she's got caught in an autorun so I'm unable to continue onwards to face the Ice Slime in the graveyard.
There were a few minor bugs I saw too (you might already be aware of), when talking to the fisherman there's some text cut off, and after talking to the girl here, she turns away from me. (At first I thought she was throwing a tantrum since we couldn't build a snowman haha)
But I'll review what I saw so far! As a disclaimer, I don't really play many rpgs and I'm not a fan of turn based battle systems so I'm probably not really your target audience, but here's my two cents anyway!
Can't say I'm a fan of starting games with an exposition of scrolling text. It's not the easiest thing to read (though I had read it from the game page anyway,) but if you asked me to repeat it I think I would have forgotten already. ^^' It's much better to show and tell, and I think it might have been more enjoyable to find these things out by exploration instead. I really enjoyed the little slices of comedy that were hidden away or from talking to npcs.
It was a little disappointing that the castle staff repeated sprites. It works fine for guards wearing helmets (and I did notice that the guards outside were mostly unique) but I think even just a recolour would have been nicer for the castle staff.
Credits at the opening is an odd, and yet cinematic choice. I did feel like I was being set up to go on a grand adventure, however the sprites and certain things like doors shaked whilst the camera scrolled, which was very offputting.
Despite being told by the Siren Guard in the Guild to interact with the books, I didn't find anything to read. This could have just been due to a lack of time though.
As I said, not a fan of turn based battles so you can imagine my dismay having to go on an errand run to kill 10 of them. I appreciate the effort you took to make it different with the Magicite and direction based battle advantages, although it's hard to tell which way slimes are looking! The sound effect from completing the quest is incredibly cheesy. It stands out a lot compared to the grand music you have playing throughout the game.
I also didn't like the quest to talk to npcs either. I felt like I was being forced to explore rather than having a choice, though I supposed it's a good way to ensure world building. Your maps really do give a good sense of a vast kingdom without actually being too vast and boring, so I think you did a really great job there!
Overall, it wouldn't be my first choice of genre to play, but I think an rpg fan is really going to enjoy this! It sounds like you've got a rather grand adventure planned and I really hope that I was wrong about the game breaking bug because it'd be a huge shame if the IGMC wasn't able to access the rest of the story you've created for it! For reference I was 24 mins in just before hitting the bug.
