Dreamer by FunnyGame is a pretty popular 1.9 level as well as one the highest rated level of Hyperbolus

The deco are amazing for it's time , it's really impressive

The gameplay is also very fun , i only have 3 complains :

1) the beginning is a bit boring

2) having the asymmetrical dual shifted to the player colours is a good idea but having the indicators as well is just a recipe for confusion , it's such an easy thing to fix , just put the indicators on a different colour !

3) the last wave's hitboxes are a bit weird

Other than that it's a really good level !
