Good, that was very polished space-invader / galaga type game with a fun little twist -- Initially I thought 'hmm, maybe this game could use some controls indicator so players can immediately see the new jumbled-up controls' but not so long after I have figured out that the finding out & getting used to the new controls was also a part of the fun this game has.
...So, I think you have gotten the control-jumbling scroll shooter idea you have told me about juuuust right!
I would really love to see more gameplay contents in it, though.. For now the game is very good for a short arcade game but I also see some potench' in this game too!
