If I were paid a penny for every Game Jam platformer where you shift dimensions... xD

Tbh, the idea is not that fresh. This game is not the worst implementation of this concept though. Even so, I really missed some visuals. The jump animation is just a walking loop which doesn't sound like a big problem in theory, but consider the floaty jumping combined with the fact that you spend more than 50% of the game in the air...

Finally, would be great to make the environment more detailed, as standard Unity cubes certainly serve as decent platforms, but look too simple for the setting.

Still, if itch.io is not lying and that's your first 3d game, it's a solid start.

I quite liked it! Switching between world was satisfying and when the invisible platforms appeared i despaired lol! I think that this really works as a base and could be expanded to even crazier levels. Maybe the only thing that could need some polish is the art but that's to be expected with a solo dev (i suck at it so i can't give meaningful tips). Keep it up!

Nice game that I liked. I loved switching mechanic. Great work and a wonderful idea. It needs better sounds and animation, and then the game will be even better

Cool take on the theme! The 3D dimension-switching mechanic is fun, and the skybox + transition effect (with the “whoosh” sound) feels satisfying and responsive.  The invisible platform section was tough. Movement feels smooth, and the floaty physics fit the space vibe. 

Runs smooth on WebGL, which is really good for a 3D platformer in the jam. The world-switching is really fun to mess with, and I liked how the levels slowly start demanding more from you instead of throwing at you all at once. The invisible section though, diabolical lol. But in a satisfying way once you figure it out. The visual and audio feedback when switching worlds is nice too. That little woosh made it feel good and responsive. Nice progression on the levels and nice feeling game as well.

Love the idea. In spite of swithcing, never made it to the third platform in the third level, but I am no good at jumping things.  But I enjoyed failing!

Hmm, very, very interesting idea! The core concept is very good and original! If this prototype ever turns into a serious game, I’ll definitely check it out! o//

About the transition: For the transition, a soft (but faster) fade in/out to black or white would fit better with the cosmic and space theme (at least for me, not a rule).

And another tip is to use the Unity’s additive mode in SceneManager.LoadScene() to toggle between the scenes, not just reload the scene again (at least I think it wasn’t additive, because sometimes the player would appear back at the origin, I could be wrong tho).

public void ToggleDimensions(string sceneName)
{
    Scene scene = SceneManager.GetSceneByName(sceneName);

    if (scene.isLoaded)
    {
        SceneManager.UnloadSceneAsync(sceneName);
    }
    else
    {
        SceneManager.LoadScene(sceneName, LoadSceneMode.Additive);
        SceneManager.SetActiveScene(SceneManager.GetSceneByName(sceneName));
    }
}

(Something like this)

Simple but nice game! I love how you iterated on each mechanic and added new things. My only issue was in the last level after jumping on the invisible platforms; I assumed the rest of the platforms would also be invisible. Maybe there should be some additional indicator that you can fall through some of the platforms? Otherwise, great game!
