✦ AI summary

Slime Must Grow is an incremental game about growing a slime by absorbing weaker creatures, with a simple core loop that some players find engaging despite its rough edges. The main complaints center on incomplete features, balancing issues, bugs introduced after updates, a clunky prestige system, and graphics that feel dated, though a few players appreciate its bite-sized gameplay and upgrade tree structure. Most players recommend it only because of its low price, with some suggesting it has potential but needs significant polish to deliver on that promise.

Slime Must Grow takes the simple pleasure of watching something tiny become overwhelmingly powerful and builds an entire incremental experience around it. Developed and published by Red Ball Markets Global, the game places you in control of a small pool of slime that begins its journey weak, slow, and surrounded by creatures that pose a genuine threat. Rather than burying the idea beneath complicated systems, the game quickly establishes its central objective: attack weaker slimes, absorb their essence, improve your abilities, and continue growing until very little can stand in your way. The active side of the gameplay revolves around using a slime ball to attack suitable targets while gradually increasing your strength. Early progress feels deliberately restrained because your slime cannot simply consume everything immediately. You need to recognize which opponents are manageable and build enough power before challenging stronger ones. This gives the opening stages a satisfying sense of vulnerability. Each upgrade makes previously dangerous creatures feel more approachable, producing the familiar incremental-game pleasure of returning to an obstacle that once seemed intimidating …

The game is missing a lot of features and some upgrades don't make sense. I kept playing to see if there was something I was missing but there wasn't. This was part of a bundle of games, otherwise I wouldn't play it. It had potential because I wanted to keep playing to see more but it just wasn't there. Graphics are not good for todays standards, even going for a gritty aesthetic its not nice to look at.

After 2.0, the game feels the same, except with more bugs. The prestige system feels clunky and forced, and i dont find it rewarding. Especially since once you beat the slime god you get locked out of any progression. The upgrade tree, is a little bit better, but has many bugs. The game is still flat, and still only recommendable because it's price is still low.

Just an awful game

Weird balancing. Takes quite a while to get going. Runs are extremely short. The artifact system seems half-baked. I can recommend it for the price, but only barely.
