I like it,tho there are tons of bugs this is just the development.
Okay things that I can tell are,
1) the health bar could be more visible(I think youll change that in future tho)
2) Enemy can be more aggressive and run, strafe, jump Idk what you can put in the game
so that we can shoot them harder while trying to avoid their bullets.
3) I think there should be a running option and a stamina bar as well. Fo faster traveling and for combat purposes.
4)Ammo and weapons info
But generally it is going well, it looks like the games we play at websites like miniclip or addictinggames. Just think of something that will make yours unique from the others,not story based only but gameplay too.
I like the bell sound when we hit them
