I like that this game maintained the same spirit of Raid on Rabbit with all the background music variations and cute game over screens. The multi-height jump system was interesting and more forgiving than Raid on Rabbit :)
I was pretty deliberately trying to make this easier than RoR, as I appreciate that not everyone likes the kind of aggressively mean platform games that were common on, say, the ZX Spectrum. Might have overcompensated a little too much there, though!
