Good job submitting something in 48 hours! that's a feat all on it's own. unfortunately this game seems to lack some of the core things that make a game. Here's a few things to make sure you have:
- a clear goal
- an adversary / obstacle
- a way of overcoming the obstacle to achieve the goal
goals can be as simple as a win flag, a score, or even just surviving
Best of luck on you next project I hope you keep designing and creating! :D
