Now first of all I will say that controller is a focus for me, that is how you played these games back in the day and I think it's important to the feel to maintain this so this is not something I plan to change. Are we intending on improving the keyboard experience on the other hand? Yes. The big planned improvement in that regard is remappable keys but aside from that I am not sure what else to do.
By the sound of it, you're not very used to tank controls which are a necessity of fixed camera angles or even more control issues arise (not even mentioning the authenticness of such controls) We do plan to look into camera-based movement but such a task was far too large to fit into the demo, so that should be able to help those who are not used to tank controls.
"The graphics could obviously use a lift" I am not really sure what you mean by this. If you mean the UI elements then true, I am happy with the inventory menu but some of the other elements could do with some more work. If you just mean the general visual style of the game... I don't know what to tell you, this is a retro 3D game, this is what you are going to get 😂 There is an option to turn off pixelisation if that is what you want but that is all you're going to get in that regard.
I am not sure I appreciate the implication you have that this was created with a lack of effort but I will give you the benefit of the doubt in this due to English clearly being a second language here. I can tell you that we have put in all of our effort in this demo but time constraints are a limiter. As we move towards full release now, we will be able to put in all our effort and the benefit of time to make this the best game it can be.
