(It's running fine on my browser if you are still worried about that)
For the first jam game it's very good. There is some polish going on. Much better then my first game haha.
I liked that there are multiple weapons. The bomb/mine is a good stuff. It saved my ass few times.
I also liked the pointer that show you direction. Very important stuff for game with large environment. It's nice that you thought about that. It gave me a clear goal.
I would increase rotation speed since it's very slow and it's hard to dodge/turn/attack. Also when you collide with enemy you are shooting past him since guns are on the side. Was it intentional? I get around it by going backwards.
In general solid entry. Congratulations and I hope to see more of your games!
Would you like to rate my game and leave some feedback? Thanks!
