Sl4sh and Fatal Error have joined forces to destroy Sonic.exe, who has been annoying them by always sticking his nose in their business. Having met Requital, the partners decided that they could use some extra help and now they are trying to get him on their side, which will be done to the rhythms of the song “Placation”.
There are three characters on the screen, and each of them corresponds to their own 4 notes. You’ll be on Sl4sh’s side, so start by finding the symbols that are specific to him (they’re on the left). Then wait until Sl4sh starts singing, and at the moments when his notes touch the stencils above, click on the necessary key corresponding to the four arrows. Try not to miss often in order to finish the musical composition to the end.
