Quite nice.
For all those having trouble winning this is a simple game to win.
First go on the platform to descend down to the three signs. Stand in the middle one until it goes all the way down, then move to the left one and wait for it to go down, same with the right sign. Now jump to the platform as the moving ones rearrange. Now go through them to the low platform and wait for the big piece of land to rise. It should be simple from now on…
Nice overall game. But needs to be harder... also a possible glitch: when trying to reach the low platform without the whole process it becomes “not solid” ground and you fall through it. Keep it up.
