Well done, it seems you made it quite far then! Yeah, I did also find that there weren't many options for weapons later on, but at that point I was very much on borrowed time. Same goes for adding firing time indicators too.
I did at first intend for the wheel to be controlled by the mouse wheel and/or A/D, but in the end I decided that the grabbing felt better, as well as being mobile friendly too. However, if we do expand upon the game, I will be sure to add it as an option.
Thank you for all the feedback, and I'm glad you enjoyed it!
