The gameplay is boring due to how boring it is, options and settings are nonexistent, their isn't even a menu. The enemies fighting mechanics are scroll down the screen and multiply with every wave, eventually my game froze because so many sprites were on the screen it just couldn't take it, have them appear in random formations with five or six at a time don't just throw more and more at the player. The graphics are uninspired, i think I've seen those sprites in every vertical shooter.
All in all this game serves no purpose and shouldn't even be active on the portal, its unfinished, has no sound, has predictable graphics and doesn't even have a menu. At the very least a game should be able to begin, play, and end, yet due to bugs and a ridiculous enemy spawn this cant even accomplish that!
With that said i still encourage you to make games, i encourage you to learn from your mistakes, to a young developer what you feedback you earn from a failure can be far more important then whatever praise you get from a success . i recommend watching ExtraCredits on YouTube, their professional insight has helped me better understand games, and im sure that as a developer what you learn could be a literal game changer.
