Thank you very much for you constructive critique. I think this jam has been more of an occasion to come up with ideas rather than making a small/short game. Hopefully next time I'll try to actually finish what I start but I'd really like to make this a full game.
I completely missed the goal, but I expected it, as it is my very first jam. Don't hesitate to rate it 0 star, it's still a submission, so I don't think it is unfair, although I agree the thing is there isn't much to say.
Have a great day!
