Not bad, a bit too straight forward... I found a shortcut that is easy to remove by putting more black floor tiles near the exit door. I recorded the unintended, and then the other run

Thanks for creating!

Thanks =), i will fix that, the second run it's exactly the intended solution.

Nice short relatively "simple test" as indicated. Very linear type of solution to the puzzle presented. Nevertheless, 4/5 and thanks for creating.
Making it more attractive with Hammer wouldn't help the puzzle - maybe add another chamber and another puzzle...?

Not sure what else to add - pretty simple, but enjoyable mechanics.
Thanks =)
