It's a solid game. This early access version takes about an hour or two to beat, including the (optional, difficult) secret content. At its core, it's a platformer. There are idle components, but they are entirely dependent on your parkour ability. There also appear to be mechanics in the game that aren't fully implemented yet - teasing at more content to come with a later release.

As far as the idle aspect... I think the implementation of the clones which run your path is really neat. All of the other upgrades are just increases to the speed at which you gain Watts, the resource in this game used to purchase upgrades. Each "stage" has a capstone whereupon reaching a certain amount of Watts, you can purchase an upgrade which allows you to do something new, like dashing and double-jumping.

There are several "secrets" in the game... challenging areas which give a rewarding boost to your Watts if you can complete them. They are generally tuned to be difficult the first time you reach them, but trivial once you clear the next area and gain a new ability. This provides a rewarding challenge for the best platformers without taking it out of reach from a more casual player.

The sound is great. The music track, the sound effects when you jump, dash, and land, they're all great.

I have two minor grievances. One, getting around could be a bit easier. I'd love to see a teleporter or something that unlocks when you reach a new zone, allowing you to easily move between zones. There's no strong reason to make me do the climb from area one to four every time I want to move around the map.

The second issue is the emergent gameplay. There are several "tricks" in the game which allow you to move in ways that are never really clearly explained. These tricky moves, if they are intended, should be integrated into the core gameplay as solutions to puzzles (potentially with tutorial) so that even casual players get exposure to them. Right now they are reserved as potentially unintended interactions seemingly caused by collision mechanics. To be clear, I DO like the emergent moves. I just think they should be taught.

You'll note both my issues have positive solutions. I'd love to see them added to the game.

I'm a fan. I probably would have paid like $5 just to play this EA version (which was free). I'm looking forward to buying the full game when it is released.
