This was an interesting concept, the art and the audio resemble those of a Gameboy game, even though the latter might look to advanced to be in one. Although there are a few points I must press on.
The 'interact' key did not seem to work. At least not as well as intended.
I had no idea I could attack if it wasn't for my random key mashing. Maybe due to a lack of any explanation whatsoever in the beginning of the game. Which brings me to the next point.
Right in the beginning, we're put in the worst of situations. Surrounded by a bunch of enemies, all attacking at once, without any sort of explanation on why we're there, what we have to do and how we can do it. And running from those enemies is futile, since the difficulty continues to be extremely unfair from then on, no matter what route you take. I don't know if I triggered the boss/big bird by using the up key or not because the transition to the room itself was totally random as well. But putting the player in such a more difficult scenario than the one they had faced before IN THE BEGINNING of the game makes them lose complete interest in the rest of it.
In sum, it's an interesting concept that needs a bunch of workarounds to look appealing, as graphics and sound don't make an entire game. Good luck!
