Thanks for your valuable feedback. Yes, I need to adjust the balancing for later levels (I wanted to add shooting enemies too but didn't get time). And I'll add the throw held weapon mechanics (I just didn't do that for the jam because of possible bugs that could happen due to the interconnected logic). Sorry about the projectile issue, I'll look into it after I add proper 3d assets in the gameplay and improve the shoot mechanic.
Thanks for playing.
