Would love to see you work further on this game as I really like this genre. My suggestion is you make the character move a bit faster as sometimes its impossible to dodge some shots. Also intrigued about the secondary ability you´ll add. Is it going to be an offensive or defensive ability?

Game jams are always difficult with time, I hope you get time to work on it some more. A few more hitboxes and sprites and I think you're there. It's great that you managed to work in a menu system, mini-tutorial, and the story pages. In terms of the game if you get more time to work on it, my tip would be to add a slightly random amount to the angle when the enemies shoot at you - that will make them seem more accurate when the player is closer and less accurate when the player is far away. Then you could position the enemies so the challenge is for the player to find somewhere good to shoot from.

I think this game concept has potential, it feels nice to go after enemies and shoot them. Unfortunately the game feels confusing and incomplete. But kudos for creating the base system for a 2D top down shooter game!
