Thank you for playing the game and for your detailed feedback! Much appreciated!
The bomb feature isn't implemented yet, but I'm aiming to complete it before the next demo day. Control remapping has been tested with generic XInput and DirectInput controllers, and I'll note the issue with F101. For modular damage, I designed the stage 1 main boss with this in mind, and I'm glad you found it intriguing. I'll consider investing more in this feature later. Collectibles are currently just cosmetic, like Christmas tree decorations, but a scoring system tied to them will be added later. I understand your point about the damage feel challenges, which is a common issue in similar games. I'll dedicate ample time to addressing this.
