that is actually funny to hear since I thought those two first levels would be too easy and people might not like it due to that.
But heres a little secret, To beat the first level, you probably can win it just by clicking the red button "Kill people" and then keep spawning robots from the bottom right spawn location when ever you can.
I am suspecting level 2 might be close to something similar as well.
Basically Idea was that third level would be first difficult level to beat, and first two be both easy just to get hang of the game. Third level is not difficult actually, as long as you are willing to sacrifice some robots, since there are lots of people trapped in that left top corner place, but that place is surrounded by weapons and some of the robots will get destroyed before you can freely kill the people, which will affect next levels too since only survived robots transfer to next levels.
Levels 3-5 are pretty much untested. I was making them last day, and when i finally took first test on them, i noticed some serious problem with them and decided to focus on something else instead since I didnt think I would be able to solve the problems in time that I had left anymore. That is also why "execute plan" which completes the game opens after level 2 already, otherwise it hadnt opened until beating level 5.
I am not sure but there is even a chance levels 3-5 are impossible to complete, since they all have coders in them that you are supposed to kill all of them to get through, however, I might have made mistake in code that it puts one too few coder in each level. Hence it might demand you to kill 3 coders, while only 2 coders are actually available to kill. On top of that, these coders are randomly placed, so they might well end up to a location where they escape the screen right at start of level, making it based upon luck if it is even possible to get them all killed, even if I didnt mess that before mentioned code.
Anyway, levels 3-5 are there just to show what I had in mind, not to be seriously played. You beat levels 1 and 2, and click "Execute Plan", and you have completed the game in its speedgame submitted form.
