This was quite fun!
I always like to see unique approaches to the old platforming format, but I think I got myself a moderate case of carpal tunnel syndrome already! (It would be interesting to have a keystroke-counter on when playing)
My older game for LudumDare45 had a similar dilemma. The controls relied on tapping and felt like a “fundamental” part of the game, but it still would be necessary to add alternative control-scheme for players who don’t have iron wrists!
I guess in your case it wouldn’t detract the experience much if applied properly.
But yeah, keep up the good work and keep trying new stuff!
