The game is fun! the idea is awesome!

However, the grenade is exactly the same as health but read and I was trying to pick it up at first :D 

This is how I loos the game for the first time))

Apart from that - Great job!

this is a really neat and fun game! though the constant randomness when shooting is a little tedious, i can say i had a good time playing this.

This game is surprisingly fun! By far the best implementation of the "randomized ammo" interpretation I've seen. The fact that the grenades hurt you means you have to keep moving and the health pickups mean that you have to sometimes change your focus to healing. While you can avoid damage without too much difficulty, one mistake means you're now scrambling for more health or it's game over. Also, you used my favorite Kevin McLeod song :)

the game is surprisingly fun to play and the concept is really interesting
it would have been better if you had added more projectiles that have different upsides and downsides
you can also implement a feature where you skip the current projectile on to the next projectile

Simple and fun! Especially like that bullets wrap round, can do some insane style shots.

I love the way you're always just playing around the hand you're dealt. A really nice main mechanic!
