Redesign of three levels

Yeaah Big update here, I improved all 3 levels.

I saw that level 1 and 3 had level design issues, and from the feedbacks I got that the levels were too long.

• Improved level 1: it is now more challenging and shorter
• Imrpoved level 3:  it is now more challenging and shorter
• Level 2 is shorter
• Corrected the damage speed of the character, it is not noticeable by the player but it would have caused me problems later
• The maps are easier to read

Next time level 4 should be playable =D
