London-based developer Portable Pixels has just released a rather cool-looking old skool Tamagotchi-esque iPhone application called Hatchi.
For those of you who weren't a child during the noughties, a Tamagotchi is a pocket-sized virtual pet that requires your constant love and attention.
Your little critter has to be fed, washed, played with, cleaned up after, and much more. Just like a real pet, you could say.
Naturally, your pet grows significantly throughout its lifetime, and will develop differently based on your level of care. Providing your care (or lack thereof) doesn't result in an untimely death, that is.
If you're up for the challenge, you can grab Hatchi from the App Store for just 69p / 99c.
