First off, thank you so much for taking the time to write this, it shows that you really care about this and that's incredible for such a small game for a game jam that means nothing in reality.
Your analysis seems decent and I'll be taking it into account when doing a balance patch. Though I don't know whether that will happen before the game jam submission as we have a lot of other more important things to do before balancing. Game Jams don't usually care about the balance due to the limited scope of the games, but if we do have a decently balanced game then we stand out a lot.
We have plans to spawn more obstacles to create more strategy and hopefully be less luck dependant. We will also move away from the luck dependence with post-jam release features involving progression and character building.
Stay tuned and don't forget to rate it on Monday at https://itch.io/jam/godot-wild-jam-36/entries
Best wishes!
