I'm not sure how this fit the theme as the timer does not feel integral to the gameplay, but it is not uninteresting as a first game at all. Though here is a bit of advice:
- Arrow keys and x is an unusual control scheme, space bar is a more usual pairing with arrows.
- the ability to restart a game like this easily without reloading the page should be implemented for a game this short with several endings, as reloading is a bit of a hassle
I hope to see more from you in future jams!
