"Opcode not yet implemented: set_text_style" for Lost Pig

[amandasaurus]

I tried to run Lost Pig and got this stack trace & error:

Pig lost! Boss say that it Grunk fault. Say Grunk forget about closing gate. Maybe boss right. Grunk not remember forgetting, but maybe Grunk just forget. Boss say Grunk go find pig, bring it back. Him say, if Grunk not bring back pig, not bring back Grunk either. Grunk like working at pig farm, so now Grunk need find pig.
