to increase gameplay variety (often good, but can distract from simplicity/ focus): increase buttons required (z, breaks), have multiple intersecting paths (the best implementation of this idea is where the speedrun is incentivised to use both paths to get the fastest time), powerup use (gravity, boosts, vehicles, etc.). Non-gameplay ways to make the track more interesting: theming, detailed visuals (which don't interfere with gameplay), secret paths (no inherent gameplay reward).

Slipryz very well designed track! Good gameplay variety through the many different ramp types, clean visuals, room to optimize for speedruns, it's overall a very enjoyable level! As for checkpoints, there's no problem in their absence due to the easy difficulty (generous room for error on jumps and limited places to fail) and relatively short track length. I think the level is perfectly fine as is, but I also will add another comment on tips for future tracks. +1

Slipryz nice +1

Slipryz I like it jj
