I had a lot of fun with this game. I'm a huge retro gaming fan, and this brought me back to the likes of Metal Storm for NES. 

The animations were cute, and the music was great. The gravity switching mechanic (and overall controls) worked great, and added some extra challenge to getting through certain paths throughout the game.

Kudos to Jampley Games for this one! I definitely recommend giving this game a try, especially if you're into that retro platforming vibe.
