My first video games were on the Atari 2600, I'm so glad to see that simple but fun 2D side-scrollers are alive and well for a new generation, born again through Flash. The Robot series is a fine addition to this genre.
This is a distillation of my least favorite task when playing a game - get the key to open the door. I didn't like it when I first encountered it in DOOM, and my dislike grew from there.
Very reminiscent of Eric Chahi's 1991 masterpiece Out of this World. For those of you who were too young to have seen it, I strongly recommend you try it if you liked this game.
Broken AI is compensated for in the higher difficulties by stacking the odds way against the player. This game is a cheap knockoff of phage wars because it doesn't add anything new, is indeed nothing but a poor copy.
I think "normal" is a little too steep for what a casual gamer expects. Otherwise I really like this game. The mechanics aren't polished as much as a Blizzard game, but very nice work overall, and the UI in particular, considering this is "just" a flash game.
