This is REALLY good. The style of this game is just amazing. The music and animations you made for the game are really good. A small thing I liked that the sound effect for the base gun are in key with the music.
The map can get a bit confusing though, and the feedback you get for breaking blocks and vines is a bit lacking (especially since it feels like whether or not they actually get destroyed is random).
On the other hand, the way you handled the gimmick of the game was really clever.
The ending was really good too btw, I don't wanna spoil it but if you played the game you know what I mean.
Overall, a really good submission and I'm shocked that it took you only 48 hours to make it!
