Hello
Thanks for the returns and comments.
About the complexity of the gameplay, your return Agradeneu is similar as others seen after demo beta testing in atari-gamer.
I'll take in count this point by modifying the contrast (colors) between the background and the first plan.
about the enemies balls, the goal is to be able to dodge them.
my priority is to ending the game "story"
about the next steps :
1) currently : definition of the last part (final boss fighting) => end of the year
2) ending game table
3) global overview of bug fixing, speed optimization, gameplay optimization (including contrast). and maybe sound optimization. (memory free space after optimizatoin allow more sounds effects, I hope)
