Bizarre! Are you on Mac, PC? Firefox worked fine on my older PC (Win 10), but I haven't tried it on my main workstation...
Thanks for playing! One thing I'm consistently running into on these game jams is a lack of time to balance the gameplay. I spend all my time making the assets and getting to run, and then run out of time! I'll try and work on that. (I may have failed again on WGJ 99 though, haha)
