Fun but simple gameplay - I did feel motivated to play several times in a row, so it works well for what it is. It looks really nice with the theater theme too. It made me laugh when I thought about it and realized the audio is a MIDI version of Godzilla by Blue Oyster Cult; it sounds good and does fit the feel of the game. Made me smile. The sound effects are very solid as well.
The theme was implemented decently well with the spotlight on a stage (taking center-stage) and the dangerous sparks falling. Nothing too central to the gameplay about lighting, but it fit the aesthetic. You may have missed the "Only One" limitation, but the precarity of having one life was a step in that direction.
Fun stuff; build on it!
