Thanks so much, Enter the Gungeon was very much an inspiration, delighted that it came across. Thrilled with your comment about the pixel art too
Always very happy to get nitpicky feedback - I find it incredibly helpful for future games, so thanks! I rarely play with a controller, so comments are really useful to me here. Granular control with the analogue sticks is a great point, and shouldn't be hard to implement for future projects - might be fun to adjust animations based on speed too!
With regards to the menu navigation, this is entirely my own fault: looking through my code, I've used is_action_pressed() rather than is_action_just_pressed() because I am an idiot. I'll leave it in it's current state during the voting period, but will try and remember to fix later!
Cheers again for the feedback, means a lot to me :)
