Hi, works perfect on a real 48k Spectrum utilising a Kempston interface - thank you! I defined the keys setting space as button 2, and then used my Kempston joystick with the space bar to drop bombs! Works really well, you should be really happy with it. Reminded me of fighting Ivy in my back garden!! Only other recommendation would be to slowly increase the speed of encroachment of the 'green mass' to keep the excitement and challenge up. Well done honestly, and thanks again :)
