Hey guys! I've released a new game that I've worked on and I'm eager to continue improving it. Please share your thoughts with me

Your job is to kill (SHMUP style) every slime that escaped the cages, the game has a wave system and currently only 1 gun. 
I'm considering extending the game so that for each number of kills, you'll have upgrades for the character and maybe access to more weapons.
Let me know if that's something that interests you! 
Alpha state - v0.0.1
