I played it a little bit more after to see if there were any other weapons but didn't get any new. I really like the movement, it's great, and it matches with the gameplay itself. The map is easy to understand, however, I think it would be better if the blue circle (you) had an arrow pointing towards the direction you are moving (something like this maybe)
Also, idk why but the shop is very bugged for me, like, I try to buy something, and it ends up buying another thing. You can check it out in the video. Talking about the shop, please make it so that you can shoot while being inside of it or make it a safe place, like a pause.
Besides that, its entertaining and definitely worth the play. :)
