Don't worry, I'm happy to wait for a more updated game.
Out of curiosity, will you be putting all the new enemies in the new 5 stages?
They will appear after level 10. I will be simply adding enemies after that level but I would recommend you replay old levels only when update 0.3 is launched.
Okay cool, I was going to play through the game again anyway once 0.2 dropped so this works out well for me!
