congrats on your first ever game! I loved it. Few tough bits but felt like a skill challenge rather than luck which is great game design. Honestly i played it without sound the first time and had to go back to check the sound for your rating and the rabbit sprite got even cuter listening to it bounce! great job! loved it. Interesting game mechanic and execution. Plenty of room for expansion or refinement!
If i had any suggestions for next steps, perhaps i might suggest that you just make the rabbit run automatically and theme your levels around that instead? It was very rare that i actually died to the light that chases you, it was almost always from miss-timing a lane change into a not quite changed yet lamp. With the exception of only a couple of levels, most of the game i spent with my finger glued to the D key and just toggled the W and S anyway. Think Bit-Trip Runner, but you know... dark and rabbity.
You could also add a foreground track too, or perhaps an endless mode that would spawn the lights (and whatever else you wanted to add) dynamically.
games like this are a joy to play and are certainly an excellent choice for a first game. Excellent job! Well done!
