Had the game's demo on my backlog for quite a while, so I'm glad to find that the game is fully released when I revisited it again! (though this also act as an unpleasant reminder of how much of a procrastinator I am).
I actually regretted I didn't play this game sooner. The story is really engaging and I found myself so immersed that I went through all the three routes in one sitting. I was worried the game would be too short or too long, but that was an unfounded worry. I think each of the route has an appropriate length and ends satisfyingly. Alto is a great protagonist and I love her dynamics with all of the boys. It's actually pretty hard to pick a favorite, though I think I like sol a little bit more because I'm weak to childhood friends tropes.
All in all, it's a great game! Kudos to all of the team for their hard works! I managed to get 5 endings so far: 3 good endings and 2 bad endings (kisha's and sol's) by accident. I wonder if there are more endings I missed, so it'll be nice if you actually release a walkthrough!
