To get to the new biome in the current demo, get a beetle to smash a block, or get to the top & drop down. As I add more to the game, i will also unlock more in the demo version! Hope i can earn your $1 !
if you wait in front of a block and a beetle charges at you, it will smash the block! but i hear you, & i'm making it easier to get into the 2nd biome for the next release
