Thank you for playing! Yes I totally agreed and some of commenters have also mentioned that auto-fire or hold-to-fire feature is needed. I'm gonna add this in future along with fixing some bugs and some other polishing.
This is our first jam, so there's still a lot to learn, but I want to say it's a great experience in all areas of gamedev at once. Be it game design or programming or making effects and music. And even marketing and promotion. The further the better!
