Thanks for playing glad you've enjoyed it ^^
I have a fondness for oldschool graphics so every time i jam i try my best to have a style that could feel authentic to this period with a few modern quirks here and there :p
the sprites are indeed rasterized models, they do have some cleanup and post treatment in gimp afterwards though to help them keep a crispy pixelated look.
Haha yeah i didn't make any of the turrets destructible cause i wanted to try and have levels where there was always some risk even if the player cleared the enemies so they are more to be considered as a stage hazard :p
