Wow, thats soo good for just 3 days, I really like the way the game looks, the different types of bullets make you strategise a bit (though fire bullets seem to be OP), I really like the concept of doing things while also shooting ghosts, and overall the game feels really polished. thought it got quite laggy at third level (web build), and I'm still not quite sure how the movement bar works, but overall It's very good. great job!
Would be cool if you'd check out my game too :)
