It’s actually a pretty standard platformer. Collect the treasures, avoid the enemies and spikes.

I’m not totally sure what the goal is, since I couldn’t quite work out how to exit the level, but I doubt it’s anything special. This game does seem to have rather uneven level designs. The above pictures show the usual screens: walk right and jump over the bad guys, or bounce off of their heads. On the other hand:

This is way too many spikes for a single screen. I couldn’t get through this part after a few tries, so I gave up and tried another screen.

In all, this is an average platformer with nothing special to set it off from the rest, as far as I can tell from playing the first level. Try it if you want to play every platformer ever, but otherwise the mario games are much more worthwhile.
