Cool game. Having a team of four must have been pretty fun! I played the game and got as far as I could, but I wasn't sure if I actually beat it, because when I beat the level with jetpack people, it gave me the option to retry or quit. I liked the music and what the idea was here, it reminded me a lot of Maplestory.
I'm glad you enjoyed it! Working with 3 other people was hectic but fun at the same time. And you did reach the end. I couldn't give it a more proper ending because of the time constraint haha. MapleStory was definitely an inspiration here.
