Thanks for the feedback, glad you liked it. I apparently made the hit indicator too subtle. When you hit an enemy your crosshair will grow briefly.
Which file did you download? I checked windowsx86 and windowsx64 and they both have a file called "Evasion Tunnel.exe" There is a Unity Crash handler executable as well but I assume Unity calls that if the game stops working.
I did? They are in the zip files
