For last challange: key is smog reduction, so build atom for energy, 3x should be enough, also mine as much metal and gas as u can. Defend with gun and flame, but build them only when u see where the mobs are going. After first day its not challenging anymore :)
Very nice design, nice overall idea. Would love to see heroes with levels, skills and items. What You definitly need is speed button !! Also agree with other comments about slowing tower<
Good game, old school, but (yea there always need to be "but" :P) a little too short. Too few upgrades and not many type of enemies. Overall 4/5. :) (btw loved that free upgrade :D )
maybe i'm blind but those bombs drops are way too hard to spot on this type of background. Also that final boss, one shooted with bomb, very anti-climatic ;) on other side very nice old school shooter deserves 5/5
lack of element of progres for me (upgrades,coins) im getting bored(maybe only me:P), also when u get few upgrades games becames silly easy coz u destroy evrything be4 it starts to fire, anyway classic arcade, old style 4/5 :)
soo nice graphics and soo terible gameplay ... too much effort in graphics, watch some games that are pixel made and got a lot of 5/5, gameplay>>>>>>look, 2/5
gr8 game but i find it not enough chellenging, not enough monsters. also more upgrades and things like jumping would make me rate 5/5, now its solid 4/5 good job :)
