Been a hot minute since I've played this game, but from what I remember, it's a blast. For a game that is nearly 30 years old, it's way more than what I expected from a gameboy game. Mario's moveset is pretty varied, and the levels hold unique power ups/abilities that change from level to level. I had thought that this game was a simple port of the arcade game over to the gameboy, but that's simply not true. Besides the first 4 levels of this game, it holds very little resemblance to the arcade cabinet that this game is based off of. If the arcade cabinet scared you off from playing this game like it did for me for a number of years, put those fears aside and try this game out.
