It's a decent platformer with with many collectibles and secrets to keep you busy.

Unfortunately the level design is bland, the difficulty too easy and the physics makes Mario feel slippery and unresponsive.

It can be a good introduction to new players of the series or platformers in general, but to me it was a bit disappointing and a step down from SMB3 and World. It's unfortunate that the next three 2D Mario games followed in the steps of this one so closely.
