Solid game with a nice loop! I would say it could use a bit more tuning with the difficulty though. Having enemies start a bit slower as well as ensuring they can't spawn on screen would definitely help!
Thank you for taking the time to play our entry and for the feedback. We were planning to tweak the settings of the game elements before we submitted, but we simply didn’t have time to do it. We’re taking all the feedback into account and will try to polish the prototype after the jam ends. :)
