Pros
Pro Powerups combine in very unique ways
There are tons of unique power ups, and most of them interact with each other to create really interesting combinations. The main attack in the game is shooting a projectile, and modifiers on top of that stack making for really interesting attacks. For example, you can have a homing, multi, laser attack that shoots in both directions by combining multiple treasures. You can build really interesting strategies this way and that keeps the game feeling fresh.
Cons
Con Can be a bit difficult to get into to begin with
A few people I've spoken to said they tried it but gave up pretty soon because they didn't get it or something along those lines. It may take a bit of getting used to, and pushing through that initial doubt to really find the fun in it, but once you find it, it's a super fun game.
