First Part
First part of Nullscapes has a raw mini robot gameplay and many frame perfects (a jump in specific frame, for example in this level there is only 60 fps frame perfects equivalent to 1 in 60 frames jump, making it very precise even for professional demon slayers). To succesfully beat the first part, you need to jump at the edge of the spikes, that's really hard, because of community got used to different type of gameplay, rather than the robot with precise timings almost at every click. At the background will be a beautiful landscape of mountains with white sky. Despite low decoration in the front, background will have many stunning views for player. Many players also tell, that entire level is really anoying and deadly hard, so except for verifier (Zoink), anybody could beat it for more than a year. So to summarize: first part has 33 frame perfects and lasts 33 seconds.
Second Part
This part, unlike the first one, is a bit more relaxed and has a different style of gameplay. It features orbs, that change every 0.2 seconds and jumps to the edge of the spikes. Background haven't changed much, comparing to the first part, but there is a fog, covering to sides of the screen and sky gradually darkens. Then everything becomes blurry and the robot starts falling in the dark. Part has 15 frame perfects and lasts 13 seconds.
Third Part
When the robot falls, the sky fully darkens and giant white moon appears in the sky. Also you can see huge black spikes in the ground and orbs, which are changing got new deco and they added micro-click gameplay and fast orb spamming (3 clicks in 1 second with 2 of them are frame perfects). Obstacles began to hallucinate and then there is a dramatic transition to the final part. Part has 17 frame perfects and lasts 17 seconds.
Fourth Part (Final)
After third part moon starts to glow and releases a giant laser beam in the sky. Gameplay glitches even more and spikes begin to fly in the sky. Gameplay ends with the robot falling onto spikes at the endscreen. Moon disappears and the screen fades to black, but the wind continues to blow in the dark. This part has 17 frame perfects and lasts 13 seconds
