oh no! what browser/platform are you using?
Viewing post in congamoeba: the amoebic friendship simulator comments
Windows 10 Home on Google Chrome Version 57.0.2987.133 (64-bit). It stopped taking keyboard input afterwards and I tried playing again only to have the same thing happen shortly after unlocking all five language characters. But apparently that Chrome version is old... I'll let you know about the latest one.
