Absolutely incredible. The work of a real pro. From sound, graphics, gameplay, everything was designed by someone who just knew what he was doing. I had so many questions regarding how to create a good game, alone, in such a short time, and this one just answers it all. I am going to bookmark this and in case I continue developing games, I am never going to forget about this absolute piece of example that it is. This touched me so much that I thought really hard if I could come up with at least some developmental feedback. About the enemy, I would like it to have an angry face like add frowned eyebrows or something that might want me to end it with a bullet. As it is now, both the player and the enemy look almost the same. Secondly, there are infinite tries. Keep 3 bullets and after that, make the enemy shoot straight at you, and then restart the level, give back 3 bullets. Basically some kind of (visual) punishment for failing. Would not have complained if adding that would have cost a few levels not to be made.
