Hey Thanks for trying it out and for the feedback!
This is my Second Jam actually. It's my first 48 hours one. My first one was 2 weeks. Sorry for the confusion.
Couldn't add one important feature (among many other things) which is aiming, lol ...
But one way to hit the enemies easily, is that you can control the fireball. Shoot first and then use the mouse quickly click/hold to grab the fireball and drag it towards the enemy, or the puzzle boxes to activate/deactive.
And thanks for the follow on Twitter! really appreciate it!
