That’s a cool little game, especially for only 2 month of game dev. Keep learning, you have a great start here!
I stopped the game whene I was nearly always invicible and dealing 40k daamages every 0.0001 seconds ahah. I Thinks you should have reduce a lot the bonus drop and especially the bombs as it become quite simple to be overpowered.
But for a start, it is nice :) !
