This is a really fun game, I enjoyed exploring the different areas! The art also looked super cool! One thing is that it's not super clear that you are looking for that red gem to scale your gun though. Other than that, great job!
I love how you combined a portal concept with scaling, it creates some really fun puzzle levels! The music and effects really work with the concept of the game too.
I really like the concept and twist on the tetris concept! The beginning concept was also really well made. I couldn't actually move the pieces though, only rotating worked.
