I was interestedd enough to watch the whole video, really dig this game scene i guess?
and here is just a few suggestions would love to see implemented
pulsating shields + bonus’s
variety of enemy types
faster slower waves of enemy
upgrade pickup’s
power station drops refuel
You can take over enemy power stations on foot combat possible ( change Camera view ) up close infantry
scroll speed differs clouds move faster than mountains
layer -3 sky (clouds ) layer Scroll
layer -2 Mountain Scroll
layer -1 City building wreckage Scroll
viewport 0
ambient combat + bombardment light flash’s to background layers
use cannons for heavy armoured and laser beams to vaporise infantary (brief flash of light skeleton then dust)
