I like the 3d feel of it and the scythe! The only thing I'd say was maybe a loude "youve been hit" sound as I couldn't tell when I was hit but it was a lot of fun! I've yet to make it past wave 2 but I'm trying for wave 3!
I never realised when testing it about the you've been hit sound, but i do agree it needs to be a touch louder. Im happy you enjoyed the game though and i hope you managed to make it past wave 3 haha.
