I'm glad you enjoyed the movement! The range limit is in place to discourage the playstyle of sitting back and sniping enemies from beyond their aggro range, since we want to encourage players to get up in the enemies' faces and outmaneuver them rather than out-ranging them. But I agree, in some cases, not being able to damage an enemy from a distance can be frustrating and we are definitely willing to look into expanding the player's range.
Weapon balance is something the we are constantly tweaking, as we introduce new enemies, upgrades and weapons. We have made some quality of life changes to the repeater and boomerang since releasing this build to bring them on par with the revolver.
Thanks for your feedback and thank you for checking our Cyber Rail!
