Thank you so much for your feedback !
I think this is not your fault, we didn’t have a lot of time to design balances levels and some indicators are missing (the cone of vision of guards should be visible for example, we will work on it!).
This control idea is very good too, we didn’t think about using the mouse for positioning the sniper, We will probably use either the right click or the wheel ;)
It is really encouraging to have such feedbacks, we definitely will keep developing game, and especially this project ! Follow us to keep in touch if you are interested :)
