Was a fun game, nice work. One thing I would recommend is a different font color for the tutorial text, yellow text over a yellowish background made it hard to read. For the sprite tearing issues where you can see little gaps between the sprites if you increase your pixels per unit by 1 it is a little hack that can make it no so apparent. If you want to know how to completely get rid of the tearing/gaps between sprites message me on discord and I can explain it.
