I'm glad you enjoyed it, we had fun creating this.
I'll try my best to give you a satisfying answer.
regarding the controls themselves, we made the choice to control each character individually through point and click, not that the other one was not possible but it was defeating the purpose of being able to position all character before ordering them to attack (automatically). This is something we will talk about for a future version of the game and why not implement two control system. Thanks for that feedback.
I'm sorry about the no damages part, since the bullet actually deals the damage, if you are literally in front of a robber's face, this might be an issue we did not take into account, we were always doing our test at a minimum range but not in a robber's face so that is something to work on. Thanks for pointing it out !
For the music we created a playlist system that doesn't loop, if the music stop you can always lunch the playlist again by pressing the space bar, i agree this is not optimal but we did not think about making it a loop system since we had about 20 minute of music and we did not think about people that would actually spend more than 20 minute inside the game but I'm glad you did. We will correct that in a future version !
To conclude, thank you for the feedback on the game, we greatly appreciate it and will definitely take all feedback to upgrade the game, glad you enjoyed at least some part of it. For the future we plan on adding more levels, a tutorial and a storyline, all the stuff that we did not have time for during the week.
Thanks again for your feedback !
