One of my top 3 for sure ! Reminds me of Geometry Wars, one of my favorite games ! The revers shooting is clever and challenging and the game is very well polished with its 5 level and endless mode ! There is definitely potential in it !
To improve it though : would be better if we have the whole map in sight in endless mode to not be taken by surprise, could be cool to have some pickups like extra life, shield and bombs :)
