Hi, thanks for playing my game! So there is an intended sequence break in the game, but it is with the whip instead of the dynamite. I think since I didn't tell the player that they could jump with the dynamite, I should have had it be a "hidden mechanic" like you mentioned instead of forcing the player to figure it out to proceed with the game.
You also make a good point about the controls on the game page. I wanted to list them since I didn't want the players to get stuck from them not knowing the controls in case they got through the instructions too quick or just forgot what key to press. I think I would fix this by having a menu you can access to rebind your keys.
I didn't implement a map for this game. As for the future of this game, I'm not sure if I want to continue working on it, or if I just want to chase a different project. If I were to update the game, I think I would try to add a map, controller support, remapping controls, coyote jump, as well as some bug fixes and some more polish.
I'll have to try out your game soon. Thanks again for taking the time to review my game!
