A walkthrough of the 2016 ZX Spectrum game, Invasive Species. Eradicate the critters then find the exit. Some creatures will have to be dispatched in colour order, and may take several hits. Others need to be pinned down before they will die. More info. and download here: https://www.worldofspectrum.org/forums/discussion/52411/
From the recording originally sent to http://www.rzxarchive.co.uk/ . Recorded using "rollback", a feature of the emulator which allows you to mark a point, which you can then roll back to later if you get into difficulty, and try again.
