Thanks for the kind words, glad you enjoyed! I realise now the health system is definitely quite unintuitive. Basically, the green bar is your health (or "rad"), and your beam and dash abilities consume rad while your swipe attack regenerates it, and the red segmented bars are your lives (or "cores") - so if your rad goes down to zero you consume one core to replenish your rad to 100%. Will definitely add a tutorial later on!
