Very fine game! I like the concept of the "story" and the gameplay. But in the end it is way to easy and why I earned skill points at level 51? For what?
This game isn't hard, actually it is kind of easy. Build some collectors, not to many because of the lack of energy, prepaire two or three blasters and send them to the creeper, meanwhile build up your base, more collectors, speed ups and reactors. The last mission is a little bit trickier, you must build faster and you need at every corner one blaster so the creepers doesn't overflood your base, after that it is easy.
Zombies...check,
Upgrades...check,
nice graphics...check,
but where's the game?
Waiting for enough money to click at the upgrape button isn't a real game for me. The thing is as player you don't need any strategy to beat the game. Upgrade, fill the army and click attack is a little poor gameplay.
Sorry, nice try, but the game is far too slow, slow fights, no real skill system, the shop is useless to make money anyway. I played up to the third badge and it was hard not to fall asleep. 2 / 5 because of the lack of gaming fun! Sorry.
Thanks guys for the comments!!
Now, after some hours I try to implent some stuff, I hope, that this will shape the game a little more.
So I have to ask you, is the bar at the bottom understandable enough?
If I have enough time the next days I will try to build a title screen.
Very nice game, especially the levelup-feature, but too short and easy. Maybe the next time the story mode needs different runlevels with other tilesets or so on. Tip: More UPGRADES! ;)
