Its pretty nice. Your gunplay is very satisfaing. Shooting a robot with the revolver in the head and the ammo and health pops out is pretty cool. But what is missing is a meele, Movement is pretty cool, aswell. The enemies have verity and its always visible who is who.
The Doom-Inspration is very visible, but not in a bad way. Most of the weapons are heavly inspired from it. Can’t really blame.
The music is where the doom inspration shines. Its really well implermented. You have a low soundtrack when you walk in corridors and when the battle begins the soundtrack gets up and kicks. Its no Mick Gordon, but its really nice for a indie game. The models and animations are really good.
The sounds are a mixed bag. Most of them sound good or great. But then there is the chaingun-sound. Please… decrease the bass or volume. Its way too loud, considering the other sounds.
But sadly there are issues.
Most notably balancing of your weapons. I had no issues playing only with the revolver and the shotgun on auto mode.
Why only shotgun in auto mode? Its way faster in auto mode to quickly shot multiple precise shots. You could, f.E., force always two shots when you shot the shotgun in auto mode or make the single shot more (visual) powerful.
Why only revolver and shotgun? Both do alot of damage for fairly little ammo consumtion. It doesn’t help that the Rifle and Chaingun use the same ammo as the revolver but do way less damage or are harder to control.
Then there is player direction. I stopped at one point over the pause menu. I don’t know if there is a actual end, you can reach. To me it looks like all levels are generated. There is no goal.
Idea: Make a visual, where the only information is, how many levels he survived. Thats it. Now you could make a goal like: “Reach Level 20 to get next time a Chaingun at the start” or something to keep the player motivated.
You are really good in what you are doing here. Just a few things to iron out. Hope I could help. :D
