A threequel where you can only collect eggs once you've painted them, with lots of enemies getting in your way, and the number of times I died after collecting some eggs, then mistiming a jump over a big gap!
I could do with a way to save at the end of each level (since the ZX Spectrum version is part of the PC game), but it is brilliant, even if it has completely frayed my nerves! :)
Also posted about it on Spectrum Computing's Other Retro Stuff section :)
