Thank you !
Yeah I think I made things a bit too harsh / not enough tips on where you should go. I'll add a mini-map and re-balance the game when the jam ends. I'm making a list of things to update / improve when I do so, so if you want to share more advice this is very welcome. Same goes if you think of cool tutorials / docs / books I could benefit from.
(I'm learning on my own and aiming at becoming a professional, so I do jams, improve, jam again... until I get more experienced and can try to sell small games (probably as a solo dev so I have to learn a bit of everything).)
