Two new stages for AmplituDS are now available. AmplituDS is based on the gameplay of Amplitude for the PlayStation 2.

Release notes:

Yes, that’s right. Two people have been hard at work to give you two new stages to play with, alongside the three new ones AmplituDS v4 already brought! So that brings up the total to…… umm…. count the one …. FIVE new stages for the fourth version of AmplituDS. Awesome.
