Fantastical Adventures

I was playing a high-speed video game as Alexander (main char from King's Quest VI). The rule of the current room was simple, but intense: Damaging lightning would spawn just in front of me in the direction I was moving, about once every second. I caught on to the pattern, and zig-zagged to counter it, occasionally messing up and getting hit. The floor was blue and had a shallow depth of standing water. This is all I remember.
