Worth a million coins!!
Mario has the perfect weight to him. He is not too heavy like Wario. He is not too light like mini-Mario ever. He walks and runs at just the right speed. He has just the right run-up to fly. He flys just right. With these bits perfect it does not need much to be very good.
The level design is fun. It may not have innovation. It may be easy. Most of the levels are fun. Stop trolling saying it is easy and samey. I've read enough of these negatives.
The power-ups are good. The fire flower works well again. The gold flower is an extended fire flower that gives you far more powerful gold fireballs. Raccoon gives you a necessary attack as well as flying and floating. If you have played Super Mario Land 2 and seen the bunny Mario, you will appreciate the attack. The white raccoon gives infinite invincibility for the course. Don't diss this for making it even easier. You can ignore the box. It is fun easy it adds.
It sounds good, has good graphics etc. I am not worried about the "new". It is the 2 that is less of it. A game of many prequels and should be reflected in the title.
