Is this the type of game you will be making? if so i suggest a original idea, not just the common shooting range sort of idea, make it some sort of interesting idea that will appeal people. I also suggest you look at more tutorials for a shop system, a leveling up system, and a talent tree system for when you level up. If you were to use this type of game and added those ideas, i would give you a 3-4/5! :)
Not bad graphics but you need more to the game, you gota add something that will make the game that much more addicting, you need some sort of money or point system that lets you upgrade your units to make them stronger, faster, or have a special ability upgrade :)
I would suggest adding a shop, or some sort of available upgrades to your gun. Also you should make more people, everyone smaller and add buildings or walls of some sort. Nice concept though, just gota spend more time on the details, for now a 3/5 :)
I have to say, this game starts off very addicting, but quickly becomes very boring because of your shop set up, if you were to make a frantic 2, you should set up some sort of leveling up system that allows you to focus more in damage, sheilds or a balance. Also you should change the look of the ship every time you buy a itom to make the game more appealing, my rating is 3.5/5 but if you were to add these features, I would raise it to a 4-4.5/5 :)
I love this game, i found very easy solutions for almost every level that were not in the tutorials i checked after, they were much more easy and that is what makes this game fun, more then one solution! :) 5/5
