After a some time I decided to KISS (Keep it simple, stupid). And I have a question: do I need to change the boss' sprite?

Creating hard level is easy. The hard part is when you have to test it.

I made a new disappearing blocks. Now they look like a balloon that inflates and swells.

Just made a new fireball for the first boss. I've never drawn fireballs before. Here is the evolution.

Level design problem Hey guys! I need your help. I made an enemy that moves only diagonally. The problem is that I don’t know how to use it in the level design (I found only 3). Maybe you will be able to find more.

The Last Enemy!!!

I am just thinking about publishing a demo version of my game. What do you think?

After a long draw-redraw, draw-redraw I finished the art of the first stage.

Demo version is released!!!

The menu of the demo version (I don't want to make buttons because it is difficult and long to do).
