The dialogue hook at the beginning was very nice. Long enough to get me interested in the game and it's story, short enough to not make me want to stop playing. Good job on that.
After that, the first thing I was greeted with was a text-based tutorial of the controls and "how to play" instructions. I'm not a fan of text tutorials. I hate reading, I like playing. So, I'd rather play and learn as I go. The actual execution of the tutorial was well done, I understood it once I read the tutorial and started playing, since the controls were really simple. The text tutorial isn't horribly front-loaded. But, I still feel like it could've been taught through play in small pieces rather than as making the player read text all at once as the very first thing they do in the game.
I really like the art, especially the silly pictures after each marriage. I also really appreciate that there were no arbitrary gender rules about marriage, that was very nice.
Some of the sound effects confused me (especially the melee character's attack sound effect). It sounded like a damage sound effect and each time I thought I took damage. When in reality, it was just the sound of an attack. So, I had a lot of trouble figuring out when I was actually damaged or not due to the SFX, unless I actually looked at my health at the top. This isn't a huge deal since the game uses pre-existing audio, but something to keep in mind in future projects.
The boss fight at the end was interesting. I saw the earlier marriages between people as active gameplay where you had an active goal of joining everyone together. You, the player, have control over how long you have to survive, since you control how fast you marry everyone. But the boss fight at the end turned to a more passive goal of "survive" where you, the player, don't have control over the gameplay beyond the light bullet hell style gameplay. The boss fight was fun, but I had a lot more fun with the gameplay prior to it since I had more control and an active goal, rather than a passive one.
Overall, the game was great and I had a lot of fun playing it. Great job and thank you for the review on my team's game you gave earlier :)
