the gameplay is really clunky, jumping is weird and there is no fun factor. You spawn, you click with your mouse like crazy until the enemy dies for some reason, and you are invincible. Overall, is not a game I would play again BUT it has nice graphics, the art style is really good and I liked the audio(too loud but nice). You could do a shooting 2d game with the same graphics(especially that 2.5D vision when outside for the first time) and better movement and more content and it would be nice!
Nice work guys! keep it up
