Yeah! First Wario platformer!

I liked the power-up system where each power-up has it's pro's and cons. I think it's a good system. Although it's kinda off-putting if you get hit once, you go back to small Wario even you have a special power-up.

Levels were fun, although some levels felt uninspired with it's enemy placements.
I like you have secrets in this game, going to speedrun this game doesn't give you the full game. Also there's secret treasures which if i hadn't completed the game i might have tried to collect them all.

Compared to Mario, some collisions have different consequences like you don't go little if you bump into an enemy. If it has a weapon, it will. Also throwing or jumping from below the enemy doesn't make you hurt as well.

I also liked that the credits scene reflects how much treasure you've collected like in Wario Land 4.

So yeah, you like Wario Land games? You can't go wrong with this one.
