It's a fun concept. I would recommend for anyone who has time to kill.
1. You just discovered post-processing, didn't you ?
The quality mode is really intense. I liked the effect, but it was too intense for me.
2. The UI does not scale.
The in-game UI didn't scale for me, so I was simply stuck to guess what the big number at the center was.
3. The controls are too simple.
Personally, i feel like this game could become competitive if it had more complex controls, in order to make dodging easier.
