Well, this is a thing that's happening
Maybe I'm just too dense to understand the symbolism behind a game that says man's ambition is dangerous, only to offer said creatures a frustrating, often unfair challenge that only said ambition can conquer. Or maybe you could just be a terrible game designer. Since we're going the artsy route here, though, you obviously didn't care about how the gameplay was going to turn out. Nevertheless, let me take a moment to point out every single flaw I encountered over the past 30 frustrating minutes.
First off, going backwards to get the bow is counterproductive. Backtracking is NEVER a good idea, even in 5-star console games, and you make it the solution to the first challenge? Even after figuring it out, what's our reward? We find out that *gasp* " ZOMGTHEBIRDWASAMOTHER! MAN IS EVIL!" Good to know we were feeling extra original and edgy today.
Our next challenge is the threat of getting sandwiched between two groups of insta-kill enemies. The only way to pass them is to wait until they disappear and to sneak by in their absence. This would be fine, except for the fact that the enemies randomly decide to disappear for periods between "enough time to live", and "enough time to screw you over", with the latter coming much more often. The worst part is, I only get two chances to slip by before I run out of time and have to do the minutes-long bird portion again. There's also no clear indication as to when they're going to disappear, or for how long. All it is is luck. It's pure luck whether I get by or get screwed because the random-number-generator decides that I need to die this time.
My biggest beef with this section, though, is that unlike the bird, THESE GUYS SERVE NO SYMBOLIC PURPOSE WHATSOEVER. They don't represent anything or mean anything to our character, and passing them doesn't resemble any kind of life challenge, so what's the point other than to pad out this empty world with some mindless challenge?
After much annoyance, I finally got to the "grim-reaper" section. I breathed a sigh of relief because I thought I was going to get something new, but unfortunately, I realized only half a second too late that it was just like the last segment: a test to see if I could react to the split second window in his instant-kill attack. And this is where I gave up on the game. I could have continued, but that's when I realized I didn't want to. I had no motivation. No conviction. What was waiting for me? Did I have a goal? Some pot of gold waiting at the end of the dark, foreboding rainbow? No. Just a chance to wade in piss for the 10,000th time whilst I continued to develop a brain tumor from listening to this goddamn song. Hania deserved better than this.
Next time you develop a game, how about you actually play it yourself before making us go through this kind of crap?
