The graphics are good, and the game works fine, but there are a couple of glitches
First off, if you click run game, it runs but the mouse is free to move outside of screen area, which makes camera movement extremely sensible, and down right unplayable. you have to click a second time for the mouse to snap into the game, and work properly
I couldnt hear any sounds, Maybe thats a problem of my computer, but if you didnt add any sound effect, I recommend you check out BFXR (https://www.bfxr.net/), its a free sound generator for videogames.
Finally, I dont see how this is related with the theme of duality
Overall, Good Job :D
