The stealth concept is very fun and takes a good opportunity to fill in an unexplored story piece! I like that it even directly references Silent Sinner in Blue with the title acronym.

I did notice that I had the fan before actually picking it up, which seemed to trivialize much of the stealth. If not for that issue, this could make for a very good stealth challenge proper.

The music sounds nice as well, and the entire game feels like a fun short Metal Gear Touhou. Well done!

love the idea of exploring whatever bullshit yuyuko got up to in ssib. i was a big fan of the manga, but that whole plotline was REALLY glossed over, so it’s nice to see an interpretation of it. sadly, the gameplay and balance issues here prevented me from really getting into it. main problem is the slow movement on yuyuko - this makes getting around the large maps quite a chore, makes the additional slowdown from resurrection butterfly really annoying, and makes it WAY more demotivating when you die. the levels are long and slow-paced, which is fine and fitting for a stealth game, but when you get sent all the way back to the beginning every time you die it becomes more frustrating than anything else. after losing 15 minutes on stage 3 due to the udonge trees’ effects wearing off with no indication for when (another problem), i couldn’t even bring myself to get back into it. this sucks even more because i was quite enjoying the story and dialogue, and really wanted to see where it went. definitely hope to see a rework, i feel like there’s some solid potential here!

Not sure how well this relates to the jam but I really love metal gear yuyuko. It's a really fun game and I loved how good the puzzles were. Also, the yuyuko sprites are cute.

Cool stealth game! I enjoyed sneaking around and finally getting my revenge on the rabbits at the end. 

I sometimes went down corridors which led to nothing. It would be cool if there was something there (like a decoration) but its not a big deal.

I'm not a stealth game person so I can't say too much about it. The second stage is a bit of a spike though, especially with the "recovery" period after you get unseen again breaking the vision visual. Also might want to make the vision field contrast better with the ground yeah. Most flaw are understandable limitation from the jam, so I'm just focusing on the one remediable easily.

I love SSiB (Reisen2 best Reisen). The Reflowering mechanic may be a bit underused when you can just shoot down everyone, haha. Overall good game !

I love stealth games! Though I think a lot could be improved on the readability on the enemies. I can't tell why certain enemies behave the way they do and a lot of their behavior is inconsistent. Perhaps in a full version you can add more kinds of sprite to teach the player about different kinds of enemy behavior. Also is it just me or is the chase really intense? Once the enemy's locked on you basically can't escape. 

It's so satisfying to finally get a weapon and be able to mow down some rabbits. Neat stealth game!

Maybe some parts of the levels could have been a bit more compact, but that's about the only complaint I have. The game is good.

Adapting a generally unseen part of the manga into a game is a great idea, especially with the genre match. Kudos to the title also being "SSIB" that's a neat touch
