Sorry if you feel this is harsh
This game has a lot of problems. Not glitch problems. There are no glitches that I could find. It's just poorly designed. The story is horribly cliche. I honestly can't imagine anything more cliche. Furthermore, there's no obvious reason why this needed to have a robot in it. Yeah, it's for robot day, but the only thing that makes it qualify is that the main character is a robot. I just think it's kind of lame that you just stuck a robot into the most cliched "save the world by collecting elements representing the four elements" scenario imaginable and think that makes it robot themed. The writing is awful. First there's the fact that you clearly don't speak English well. If you're going to make a game in English that contains writing and don't know how to speak it, find someone who can speak it and have them do the writing for you. Second problem with the writing is that, like the story, it's horribly cliched. It's like you weren't even trying to make it interesting at all. The characters were "OMG I'm the hero Ima save the world" and "OMG I'm the bad guy I'm kill everything just because" and 3 "Ooo, you're the destined hero." There was no character development at all. Yeah, I know it's just a flash game, but that doesn't mean it has to be flat and uninteresting. The gameplay was horribly simplistic as well. You slowly progress from uneventful screen to uneventful screen until suddenly you get an item that seems to do nothing. I was thinking the game might have promise when the wind item actually did something, but then it wore off after two screens. That was lame. Most of the game is just bland walking and those two screens in the fire world were basically just a brief platforming minigame. One that only lasted two screens. How boring. The rest of the game should have had challenges like those two screens. The key minigame was interesting, but you could have done more with it, and it should have appeared a couple of times throughout the journey instead of in one spot. Then there was the boss. My, what horrible design. The bullets that fired directly straight were undodgeable. Jumping, they would hit your feet, not jumping, they would hit your head. It didn't look like they did, but my health bar went down just the same. Some of the other bullets were impossible to jump over as well. Once the wind phase started, it became possible to dodge a few more bullets, but dodging certain ones required timing that made it impossible to dodge others. The the next phase is a matter of being in the right spot and jumping at certain intervals to dodge every bullet. Then you just end the boss fight. Honestly, the design of the entire game suggested it was either incredibly rushed or you just didn't care. And the medals? Well I got the one for the elevator, and the two for winning and losing the boss fight, and for the end of the game, but what could the other two possibly be? I replayed the awful thing and won without dying. I certainly hope you don't expect anyone to beat it without getting hurt, because as I explained, that's not possible due to poor design. I clicked every link I could find, looked for easter eggs, but the game is so simple, I'm not surprised I didn't find any. What's left to do? Furthermore, why do any of the medals have to be secret, seeing as most of them are story based? Whatever. The one thing the game had going for it was the art, which was good I guess, but come on, it's been done a million times before. You did the old school 8-bit style right, but it isn't original at all. So even the art doesn't redeem the game, not that art alone could redeem a game like this. Overall, every part of the game showed a major lack of creativity and very little thought in the design. I'm sorry if you think this is harsh. I'm just being honest, and if you want to seriously design games, you're going to want to accept criticism and take what I and other people have said here into account when you make your next game.
