I liked the idea of getting a twist of Space Invaders! The game as intended is a fast-paced arcade shooter when you need to survive and defend yourself at the same time. I would added a faster roll in my opinion. If you play as not intended, you can reload bullets out of bounds and also being on the left on the cantina and staying there and shooting every time and you can defeat everyone who pass on there without risks. Tips for improving this: if the enemies can leave, it’s game over, so you need to defend your base somehow. Limit the movement the player can do and make sure the player is not safe anywhere. When the game refresh the screen there is a chance (especially if you click on the screen) to crash the game. Thank you for making the game, just fix the bugs I indicated and your game will be even better :)
