Great twist on the original. I like how much you made it your own while keeping lots of the original elements.
I dont think I could find an end state, after lighting up all the letters it just kept going. Also while you copied all the UI elements from the original (lives/energy/etc) they didnt do anything, so it would have almost been better not to have them.
The colliders were a bit rough when it came to jumping landing, but that didnt make the game harder or distract from the flow as movement still worked quite well.
I liked that the letters actually light up the sorroundings but the colour choice might have been better with something other than yellow on a white background as it made it quite hard to see the platforms.
Was there any sound/sfx? I couldnt hear any…
