Okay! Grooly I am definitely feeling this game bro bro! This is a very interesting game I was always fascinated with the type of games that involved drawings coming to life! There are a few things I want to touch upon though because there is a reason I didn't give the game 5 stars.
First this game is a bit buggy. I believe I made it to the end but I couldn't finish it due to the game glitching making me have to refresh my page which started the game all over. So to compensate for this problem I advise you put some type of save system so players can start where they left off. Furthermore when you die and an enemy is attacking you even when your dead it makes the death sound constantly repeat over and over( Which gets pretty annoying real fast). That's what I think caused the glitching but that's just a theory.
Second I feel as though this game could have a more vigorous soundtrack if you need some music message me and I'm pretty sure we can work something out (I know people that make game soundtracks).
Overall the game itself is pretty unique the art design and the difficulty keeps it very entertaining. Especially when the creator is just constantly drawling more and more enemies onto the screen. I also give you more props because you used the unity engine.
Final score: 4/5
