I think you should be able to hold down the shoot button to rapid fire. The enemies should have a tile around where they spawn. 

The movement felt good and I liked the sound effects. 

Adorable sound!

You should randomize spawn positions of enemies, as there is a very simple tactic to win the game now: just stay in the center and shoot to the corners one by one.

Congrats for your first game jam! It was quite fun! I enjoyed it! I loved the sounds :)

I may be a sucker for vampire-survivor-likes, but this was pretty fun! I honestly think the sound effects add to the charm & the artstyle, (while minimalist) is consistent. A respectable title for one of your first games :)

Fast to grasp who is enemy and who is player. Nice sound effects, like it.

The camera could be a bit smoother might add some lagg to it. The arrows could be pointing in the direction they are moving. Sometimes a bit hard to see where they are going.
