Has potential, but it lacks so much polish. The difficulty that it has makes it unfun to play any more than two rounds, both of which only lasted twenty seconds at best. There's just no warning where the spikes are coming from, and they move so fast. If you're near a wall, it can spawn right next to you and instakill you with no time for you to react. There needs to be more indication of where the spikes are going to spawn, so you at least have a little time to react.
Some things are good, such as the title screen and the smooth player movement. I actually may use that in another game myself. It feels great and still is fast enough to avoid things if the spikes weren't moving at hypersonic speeds.
My advice: Add more spikes that do different things that slowly join in over time to make it more difficult. The single spike is too fast, and too unpredictable. Score could be based on how long you survive.
All in all, this game has a great start, but at the moment is borderline unplayable (hence the low score).
