You had some of the right stuff.
The game's core was okay. The gameplay was simple, at best, and I imagine that's what you were aiming for anyway, so its okay. The graphics, because they were intentionally this way, were good for pixil art. However, there were a number of small issues that added up.
First, there was no opining menu or anything like that, the game just STARTS. while the menu is hardly a necessity, its a nice feature to have and makes the game seem more professional.
Secondly, you needed some kind of death animation. When you died and just showed up at the beginning, it was confusing, especally sense a lot of the times you don't know what killed you. Monsters would move suddenly and so quickly that you were jumping over a ridge and suddenly you were at the begining again. Also, I would recommend you make the traps and such easier to see. I died five times before I even noticed the spikes I was constantly jumping in.
Thirdly, the gameplay itself was simple and not very interesting. Whats the motivation? Nowadays you need more than just the feeling of accomplishment in order to try to win a game. The gameplay was too boring and dull to waste much time trying to finish. You moved slowly, there was no music, and sometimes you had no idea what was going on till you died five times.
At its core, this is a platforming game with little to nothing new to offer its audiance, except some frustrating moments and ultimatly easy, if not confusing, gameplay.
=3 Keep trying. You'll do better next time.
thanks!
