Thanks! Yeah It's not done yet- planning on fleshing out levels significantly, this is just a test of the mechanics and making sure I can upload and publish successfully really! I have about 24 hours on the clock for the jam luckily.
Gems also spawn bullets when you shoot, so that you can create bullet hells for your enemies. All while needing to avoid being having the enemies pushed into you. I'm hoping the level design I do will help intuit how best to use them.
