Thanks for your kind comment, really appreciated!
Yes, we made the game during the last week-end only, but we are quite experienced jammers and we were using some optimized-for-jam tools our main programmer Mahjoub is developing.
I also participated to the last LOWREZJAM, so I knew in advance how to initialize quite a few things needed for this jam.
This whole setup really helped us a lot in speeding the whole process.
