Thank you very much for your long comment, it's very appreciated.
I'll try to get the team together to see if we could do a little patch with all the feedbacks we now have.
But as you know, it was for a training course that is now finished and everyone returned back home. I'll keep you updated because a little help for the english translation would be appreciated, haha !
We had a few more game mechanics too (coded and all) but we decided to cut these out because of time constraint (we had only a few weeks with all the learning aside).
PS: My personal record for the "speed-run" of our game is 01:50 ;)
