Hello "Ulric", i see you have potential, but just not putting enough into this. It's adequate. But try to make an actual shooter or gadget by putting a lot of time in it.
Not saying it's bad, but it's not good either. Try to work on this skill of yours it can create beautiful things, your imagination. You just need to find the means in which to portray it. That is all, thank you for reading this.
Not that good
It works, but it's not that good, you can't see where the bullet fired, and there is no muzzle flash, the collision detection is not very good, if you make version 2 of this, I recommend adding the things I mentioned. FINAL SCORE: 2/5 and 5/10
