Its a really good game! You should maybe add music, and if you stick with this type of games I would suggest Evan King's music. You should also work on camera movement so it is more  fluid and the players can see more of the game because I cant predict where the enemy object are. Overall it is a really good game! Could also give some feedback on my first game? 

I played the game and it's a very cool result for the first game. Platforming is neat and level design is simple, but working. Good that you added some sounds, particles for exit and a glow effect. The game actually looks not bad, if you polish the visuals a bit, you can make some good looking minimalistic style. Like in Thomas Was Alone. Looking forward to what you do next.
