I was lucky enough to receive an early key for the game. Thank you very much for that, Gentle Giant!

All I'll say is that, based on the Steam page, you would think this game is pretty small. It's a layered game, similar to Fez, Tunic, Animal Well, etc. so you *can* get to one stopping point after ~10 or so hours, but there is SOOOO much more than that. I can honestly tell you, as someone who has been obsessed with videogame secrets my entire life, this is without a doubt one of my favorite games of all time. It's got so much to it: knowledge-gated abilities that will blow your mind, elements of Fez, elements of Tunic, elements of La-Mulana, elements of Animal Well, a few lingering mysteries - all wrapped up in a package all its own.

I'm also someone who really does not like playing platforming games with a mouse and keyboard. I grew up playing them with a controller, am used to that, and still play them with that - except this one. Monomoon controls absolutely perfectly with a m/kb and I never once through my 75+ hours (so far) in this world thought, "man, I really wish the controller worked as well for this game as m/kb!" I didn't even TRY controller because I didn't care to. The m/kb controls are perfect and the character is a joy to move around through the world.
Despite me deciding not to bother using a controller throughout the game, it does perform well with one. There are only a few challenges here and there that might be easier with a mouse.

Speaking of mouse and keyboard - you could even play this as a couch co-op game, with one person controlling the character movement and another person using a mouse or controller for the moon. It actually works quite well!

If you are even a little bit interested in metroidbrainias or games loaded with secrets then get this game. It's an absolute steal at only $12 and is one of the finest examples of the genre ever produced. 9.8/10

This looks to be the next step for the genre after Animal Well. It incorporate the best parts of Tunic and a few other games in the genre in a less subtle way, but also forgoes the heavy reliance on illusory walls from what I've seen so far

Barely an hour in but I'm already sold. If finishing Animal Well left an empty space in your heart, you might want to check out MONOMOON right away. I'm playing on PC and the keyboard + mouse mechanics are delightful (not sure how this translates to gamepads or the Steam Deck yet).

The scenery is beautiful and lively, there are tons of carefully animated pixels you can't easily catch on the gameplay video. Music is enchanting. Puzzles so far are clever. The whole package is strong and polished.

Well done, team. This is another likely indie hit proving that a small team of creative devs with a strong vision are unstoppable 💪
