I'm surprised this was done in just 4 days! I read someone who reached loop 18, I can barely pass loop 6 ><
Is this game endless or is there a loop when you reallly beat the turtle?
It's "endless" but there is likley a hard cap where the enemy spawns will be greater than the weapon fire rate, (or the sheer amount of eels crashes your game.) I have never gotten past loop 9 myself.
