It's really nice to read your comment, I really appreciate it.
Yeah, i think the intro could be faster or skipeable, but then i thought, it's a jam game and my game lasts 5-10min and you not gonna play it again because has 0 replayability, but it's a good point.
I don't know how you lost the ability to plant flags but they are not really necessary if you have a bit of patience and skill, but i'm really sorry about that.
With the ending i wanted to do a plot twist, the only info you have it's that you must to climb this mountaint but you don't know why, then because the game is so short maybe the ending it's a bit weird. But i think it's good for me if you feel uncomfortable, it's a valid feeling when you end.
I really appreciate your time to play and give some feedback, i'm trying to learn a lot of gamedev and this helps me so much!
