There's no doubt that Rain World is a divisive game. It's very much a love it or hate it kind of game, but it's undeniably a unique labor of love and if it clicks with you, it's one of the most interesting entries in its genre. For me, Rain World is one of the best indie games ever made.
Gameplay-wise, Rain World is a gargantuan metroidvania, a metroidvania where you have all your abilities from the start and the "keys" that unlock new areas are your skills as a player and your knowledge of the world. It's a metroidvania with hundreds upon hundreds of handcrafted rooms divided among incredibly diverse regions, inhabited by a dynamic ecosystem brought to life with fluid procedurally-generated animations and intelligent AI
Relentless hunters, camouflaged stalkers, creatures at home in the murky depths and open skies, things lurking in places where the sun never shines...Rain World's industrial jungle is home to predators and prey of all kinds. An intelligent civilization existed before, but now only the decayed ruins and eroded infrastructure remain as remnants of that long-gone culture. Oppressive darkness, dank rusting cisterns, rolling hills of detritus, metropolitan ruins, and much more are waiting to be explored
But most importantly, it's a game where you play as prey. It's a game where progress and survival hinges on getting into the mindset of a prey animal, that you're near the bottom of the food chain. If you don't adapt and acclimate to that cautious careful pace, to the feeling of being weak and outnumbered and surrounded on all sides by threats that can kill you in a second, Rain World can be very frustrating. But if that "depowerment fantasy" appeals to you, Rain World is unlike anything else.
I could discuss Rain World for a long time but Kansoku did a fantastic detailed thread write-up about the game last year, covering the design of the world, the complex behind-the-scenes tech behind the AI and animations, the sense of discovery and mastery

One major aspect of Rain World, is the fact that you have an entire ecosystem simulated. Every individual creature has it's own behavior and they're being simulated even if they're not on the screen. So you have all these creatures, each different from the other, even within the same type of creature (like, some have better vision then others, for example), and they're moving around, interacting with other creatures, all in the background, so when you move to another screen you might not know what you're going to see. It really sells the living world aspect, it really makes you feel that all those creatures are the same as you; they're going around, searching for food until the next rain season comes. And to sell that even more, the creature designs are procedurally generated, and all the animations (including the player) are a mix of handcrafted and procedurally generated. So each creature is unique in it's behavior and appearance, and due to the procedural animations, they can respond to all the different situations they'll get in.
The technical aspects of Rain World, the complex AI, the simulation in the background, the procedural animation, is what sold me initially on the game. The mechanics of the moment to moment gameplay made me stay, but the beautiful world and the story (especially the ending) elevated a fantastic game to a must play one.
I'm not sure I managed to sell this, as it is quite hard to put into words, especially without spoiling anything. But even if you're not that interest in this type of gameplay, or think this game is ugly, or whatever the reason you have for not wanting to play, I still think it's worth checking it out just to see it's world come alive. The developers managed to do something quite amazing, and it bothers me that it's getting so overlooked.
