Played it a little further now and even beat some of the levels. Really fun mechanics and amazing graphics! 

This is one of my top favorites from the gamejam so far! The music is sooo freakin good! I've actually hooked my GBA-SP up to our studio monitors just to get the full range of this awesomeness!! And the game mechanics are really fun and intuitive!

 I'm loving the turnip weapon pickups, and it seems all the enemies are all very intelligent! I was amazed at how you had programmed each of their individual "personalities"! For real - this is an absolute gem of a game right here!

I'm looking forward to beating it!

(unless the game beats me......)

Love the game at first glance. However, in the Abandoned House I couldn't get up the wall at the left of the bottom. I had the idea you might have to move the jumpy blob to it, but I couldn't pick it up with 'B', because as soon as I got close it bumped me up. Is that a bug or do I have the wrong idea?

It was not so clear what to do, also i couldn't shoot, don't know if there is something i need to pick before shoot. I like the colors and the music, even when it's the same the speed change gives it another feel. Congratulations on this.

Really great job on this! Love the variety and attention to detail. Impressive use of colour too.
Definitely feels like you're pushing the boundaries of what can be done in GB Studio.
