Ratings and reviews

Having played thru once, I'll say this: it's unique. Like some Tamagotchi from hell, you balance the nurturing of a thing growing out of one arm, the questionable advice from a watch on the other, and the occasional prodding of a hacker trying to take the whole thing down...all rendered in glorious 16-bitery. Odd, but interesting.

very interesting! i don't have the patience to go through and try to get a bunch of endings, but for the time i played this was a very interesting and unique game. the art style is nice, and it's fairly easy to understand what to do. i know tons of ads tend to be a problem in mobile games these days, but i don't think the ones in this one are overbearing. plus, i kind of like the way they announce an ad is about to start. definitely recommend.

Great quirky horror game, obsessed over getting every ending despite the monotony of the minigame aspect (I flicked a lot of robot parts across my screen very fast for longer than I should've) but I loved it and look forward to more development and translation from this developer. (PSA: IF YOU TRY TO PLAY THE OTHER GAMES DO NOT REVIEW BOMB THEM FOR NOT BEING TRANSLATED YET MOST OF THEM AREN'T. Give the dev a break ffs.)
