Some games are quietly captivating. They don’t bombard you with complicated rules, penalize exploration, or make simple movement a struggle. The Secret of Crystal Mountain, a new platforming RPG created by Chris Rosenthal (Revolutron), is one of those games. I recently had a chance to play a demo at PAX East 2026, and its beautifully simple world offered a refreshing change of pace in a genre that often feels overly complex.
You’re a Delivery Cat who’s had a rough landing on Crystal Mountain Isle. This island used to be famous for its magic crystals, sending them all over the world to witches and wizards. But then, the crystals suddenly stopped being exported, and the island fell silent. Now you’re stuck there, and it’s up to you to figure out what happened.
“You’re not fully aware of the situation,” Rosenthal explained. “But as time goes on, you’ll start to understand.”
This system achieves a lot with minimal resources, and I found it fascinating from the start. That initial interest kept me engaged throughout the entire demonstration.
A Platformer That Meets You Where You Are

From the very beginning, The Secret of Crystal Mountain makes it clear it’s not about challenging your skills, and that’s intentional. The developer designed the game to focus on player choice and exploration. As they put it, the game isn’t about mastering difficult jumps, but about choosing the path you want to take. Levels often offer multiple routes, and you have a variety of movement abilities you can combine to get there.
This design philosophy is evident throughout the game. Moving your character feels natural and allows for a lot of creative freedom – it really encourages you to try different things. Even when I failed, like missing a jump, the game didn’t punish me with lost health. Instead, I quickly reappeared at a safe location. It’s a minor detail, but it makes a big difference. The game values your time and keeps you moving forward.
Dying in the game doesn’t feel like a major failure, but more like a fresh start. When my character died, I only lost a small amount of in-game money, which felt fair. There’s enough of a penalty to make you care, but it’s not so harsh that it’s discouraging after a tough experience.
Old-School Exploration Energy

To be honest, there were times during the demo where I felt completely lost and wasn’t sure where to go next. I’d stumble into an area, look around, and have to figure out the way forward on my own. That feeling of mild confusion about where to go is something I’m used to, and probably anyone who played classic N64 and PlayStation platformers like Banjo-Kazooie, Spyro, and Crystal Mountain will recognize it too. (I did eventually manage to find my way, though!)
That brief moment of confusion actually felt good. Overcoming it made finally understanding the game feel really rewarding. Once you get how things work, it all feels natural, even if it takes a little time to figure out.
If you get stuck while playing, the game has a helpful feature to get you moving again. You can often buy silver keys in shops, which unlock doors and areas that are causing trouble. This is a great way to ensure the game never feels impossible, and it’s perfect for players who prefer exploring to challenging puzzles. I can already picture my seven-year-old son using this feature when he gets to try the game!
Lush Without Being Loud

The Secret of Crystal Mountain has a striking visual style that’s surprisingly difficult to achieve. While the game uses a simple, clean design with clear environments, it also manages to feel rich and full. The island is particularly beautiful, featuring glowing blue crystal towers rising from lush tropical plants. The wide-open areas encourage players to explore, creating a world that feels inviting and immersive – like a place you’d want to visit and stay a while.
“I really like how simple it feels, but it’s still full of interesting details,” I said to Rosenthal while he was showing me how it worked. He chuckled and replied, “That’s exactly what I was aiming for – rich and detailed, but not too much.”
The most memorable part of the demo was definitely the ability to control birds. Around two-thirds of the way through a normal game (but earlier in this demo version), you learn a song that lets you take over birds flying around the world. This feature works well with the game’s core idea: as you explore, you discover songs which are added to a songbook, and each song unlocks new ways to interact with the environment.
Taking control of a bird and flying over the landscape was a surprisingly amazing experience. It’s not only a fun way to get around, but it also feels like a natural part of this magical island. Each new ability you unlock changes how you explore and interact with the world, which really adds to the feeling of magic.
A Solo Act Worth Watching

It’s remarkable that The Secret of Crystal Mountain was primarily created by one person over three years. Considering the length of development and that it was a solo project, the game’s scope and quality, based on the version I played, are truly impressive.
The game is planned to launch on PC (Windows and Mac) and Nintendo Switch in late 2026, and you can add it to your Steam Wishlist now. Even in its early preview version, The Secret of Crystal Mountain is surprisingly rewarding for how simple it is. I expect the full game will deliver even more of that comforting, classic platforming experience I’ve been craving.
