I like the visuals. The controls are simple (in a good way) and new to me.
On the downside, I can't fit the entire game on my desktop screen.
Also, I felt like I was often getting killed by red stars and spikes when I wasn't near them. Maybe play with the hit boxes and give the player a little mercy? It's always nice to get close to being killed, but not actually get killed. It's frustrating to feel like you weren't close to getting killed and then get killed.
Anyway, nice job!
