For 14 you should be very proud of this
I did find it a bit difficult to kill enemies.
But a full upgrade tree, pretty amazing for your first 2D game!
Thank you so much! I really appreciate your comment. And I'm definitely proud of this. I did make a few 3D games before this, but this was the first time I made a 2D one. And yes, I also noticed that killing enemies was harder than it should be, and I couldn't figure out why this exactly was happening. I would've definitely fixed that if I had more time. Again, thanks for your kind words!
