Very cool game. One of me favorites.
The core is very simple but it works, what makes it really amazing.
The OST matches the puzzle vibe.
I didn't manage to beat it yet.
I'd like to point out a few bugs:
- If you lose in an advanced wave and try again, the variable that controls how much suns you spend to move the planets is not reseted into first expansion.
- If you click into the credits, there is no way back.
Great work for a week!
