Gave this one a shot this morning after my team mate said it was a lot of fun - the gameplay was great and reminded me a lot of Unreal Tournament/Quake. Even the map design seemed right out of the Epic playbook. 

It would have been nice to get some idea of when an enemy was nearing death, just for player feedback. :)

Really great gameplay and aesthetic

I found myself simply just wanting to spam the bomb skill once the skulls grouped up. I think if somehow I wasn't backpeddling so much, that'd enhance the game.

As Adam said down below, I wish there was some indicator to know when the skull is going to die.

As I said in another review, I genuinely suck at these type of games on account of rarely ever playing FPSs, but even I can see this is really well put together. I found it a bit strange that the skulls kept spawning right behind me, so in the first minute I didn't even know why I'm hurting. In any case, good stuff!

Great retro visuals and sound - as a fan of Doom and Wolfenstein i approve this game :D 

Really great game!! Love the visual style! Took a bit of time for me to get the hang of it, but managed to kill many of the skulls. Got up to 30 kills!!! :D I could totally see this being turned into a full game.

Only thing I would say is that when firing the gun I was never sure if I was doing any damage at at all to enemies, as there was no visual feedback. 

Took me a while to work out how to use the abilities other than the gun, also found it a little difficult to work out if I was doing damage or anything to the enemies. The visuals though were great, so overall I had a good time with the game. Managed to kill about twenty skulls

I loved the visuals for this game, very nostalgic. Well done!
