haha, this was fun.
A couple of comments:
- The crosshairs for our aiming should definitely be LARGER! With all what's going on in the screen it's too hard to see where we are aiming
- The difficulty curve is a bit steep, too many robo-balls spawn too quickly I feel like straight away
- Also a bit unfair that they spawn randomly near you and can kill you right away. They should spawn off screen or near the edge to simulate the effect of being alerted to your presence and coming to get you (from somewhere else - we don't care)
- I agree with the comment about the 'vanishing' wall pieces so we can still see the character. I kept thinking I'm opening a door I'm supposed to walk through
- Also... LOL I know everyone is supposed to interpret the theme freely as they see fit, but still... the adherence to the theme I felt was quite 'weak'
But anyway, good effort, I'm also a UE4 user and it was enjoyable to see what others could come up with using it!
