Does the developer not care about slugs anymore ### 4/5 — a bit boring but its a sea slug *2021-06-11, version 2.1* would love if i could do more with the slug. just a little friend and all, but all they do is move and eat, but that’s okay. maybe adding decorations, having multiple slugs or shortening growth times, being able to get your own slugs, like exploring to get them. get different foods for your friend, name them, etc. would love more nudibranch games ### 5/5 — I would pay to remove the ads! *2019-03-11, version 2.1* I love the nudibranch. Now I get a digipet one! What could be better? I cherish the sea slug just like the opening greeting says. I seriously would pay for a version without the ads at the bottom. They take away from the setting and feel. ### 5/5 — AAAAAAAAAAAAA *2017-12-09, version 2.1* I love the game I really do but MY GOD IT KILLS ME WHEN I SPEND 78 DAYS FEEDING IT AND IT DIES BECAUSE MY PHONE DIED 10/10 would recommend ### 5/5 — Great game *2015-09-20, version 2.0* I really enjoy having a little sea slug and I can't wait for it to spawn and get a baby! xD ### 4/5 — Great game.... But.... *2015-04-25, version 2.0* I've had this game before and I was able to get through about 3 generations before I had to get a new iPod. I have iOS 6 so that might be the issue, but I've kept my sea slug/snail alive for 45 days twice, because one died on accident, and it still isn't successful..... :/ ### 1/5 — Davey *2014-11-28, version 2.0* Worst game ever. I've been playing for two weeks and all it does is sit there. It refuses to eat the bait that I put. ### 3/5 — It's ok *2014-06-25, version 2.0* The translation is bad, but you can still understand most of it. If you forget to feed it for a day it dies, which makes it difficult. It also takes 25 days before it can spawn. Otherwise it's a fine game. There could be more ways to interact with and view the sea slug though. ### 3/5 — Hard *2013-11-22, version 2.0* It can be hard to keep track of your snail but if you feed it 1 or 2 times every day you can get further that's all I'm saying because I don't want to ruin the game. So if you like caring games this might be for you or if you like challenges. ### 5/5 — It's a good, relaxing game *2013-09-07, version 1.8.5* A lot of people give this game crap, but it's really good. All of my sea slugs spawned around 25 days old and they create lovely color combinations. I just visit them once a day and feed them, that's it. It's more like something you can do to pass time and distract yourself. I love how each day the sea slug visibly gets bigger and you can see its pattern better. A good game in my opinion. ## Frequently asked questions about Umitan ### How do I feed my Umitan?
