I'm writing and coding the game and prototype is already working perfectly with these sketches (i will post a sketched version later/soon) - i alredy gathered all music and sounds and it seems that i just need to finish the drawings now!
on these sketches:
1) first level monsters - cyberpunk Zombies and Zombie boss. There will be a twist - you will be able to defeat the big daddy using...other methods
2) Van Helsing is a kick master. You will be kicking zombies left and right before reaching the final boss of first stage.
3) Van Helsing has a cool device - Communication and First Aid system. It was kinda inspired by PipBoy from Fallout but i added lots of personal stuff - it's more related to japanese mobile devices of 00s!
