Thanks for your good feedback.

Hah, I made it down there. While that area you hinted at struck me odd before, I never looked there. Once you gave the hint I immediatly knew where to look.
Anyway, nice architecture and a great secret hunt.

I mean the floor on which the player starts.

There is something hidden on the first floor of the Level which must be activated.

As a recap: I found both green secrets (both in the inside area, small ledge wall and hole in the ground), both orange secrets (on the very top and also by climbing below the stage on one of the four sides) as well as one red secret (riding down the platform from the very top). Now I can't figure out how to advance (I guess I have to travel somehow further down the level). My latest "clue" are the four areas below the main level: One area with the aforementioned red secret, one with the orange cube, one with two Building Blocks and the last one with an Activation Cube (which powers another platform below the stage). I don't really want an indepth solution but more of a small hint on how to go further down. It is time consuming to try things out, since it is usually required to travel across the whole level.

I do not understand what you already visited. Do you have found both green and both orange secrets?

Any small hints on how to get to the lowest area? I visited all sides below the starting area, one with an Activation Cube, moving a platform from below the level to an Energy Cube. I can't figure out how to go on from there. I have one Energy Cube total (to either use it on the top platform or the "below main level"-platform), multiple Building Cubes, a Gravity Cube and a Force Cube.

It's lagging so much and for some reason that makes it so I can jump over 2 blocks

Nice that you like the Level. I am very curious if you can find one or both red hazard blocks :)

I liked the level overall! the only annoying part was the one where you bump your head all the time, I hate jumping like that.

These are the hidden cubes I found on my first playthrough.
