A very interesting game, to say the least.
The premise is really intriguing, and the game capitalizes on it with interesting choices that actually matter. I spent a more-than-decent bit of time deciding what choice to pick!
The music and sound design is spot on, captures the atmosphere very well, with each scene.
The gameplay was well paced for the most part, didn't get stale like some RPGs sometimes get.
The portrait art is great, both hand drawn and ai generated(?) [the alien portraits felt distinct, which fits well!] it has a neat style to it. The pixelart felt a bit bland at times, where the alien's world especially could've been better with more unique shapes and symbols, and decorations more like the houses and towers. A more restrictive colour palette for the alien world especially could accentuate the vibe of Alkia. I loved how the Holl looked, reminiscent of Ao Oni's monsters, freaky and, fittingly enough, very alien.
There were a few minor visual bugs:
The character's head clipping onto the doorways, the chairs looked a bit odd with how the player walks through them [common in rpgmaker, but still odd nonetheless]. The ginger guy's character portrait has a stray line extending to the side in a few expression slides.
I'll just mention that I haven't fully beat the game yet, and just wanted to get my thoughts out before I forgot them, I'll probably edit this once I finish the game :]
Alright!
So, after getting a few different endings, I'm quite interested in seeing all seven, I'll edit again once I get them/find a video of them
