And I also find that the demo level of this is way harder for me. Stele, a copy of this game with different graphics and without the editors, I can beat more quicker. It requires VERY PRECISE timing in order to get past the spikes, because 99% of the time, I miss those green balls that make you reach the green heart and finish the level. TIC-80 really needs savestate support!
I wonder why you never released this on the TIC-80 website before Stele was released.
