i feel you, handling controls can be a cruel task, i hope you can find the right mix. tho do think about letting the player be as much in control as possible, especially movement. its the first thing you experience in a game it can definitively make or break a game, it HAS to feel good. its the other elements that have to adapt to it, not the other way around. its ok tho if the game is too easy, its a jam game, there’s a bit of “showing off your work” to it, if its too hard it basically become a player filter, and you cant really afford to filter a small playerbase :)
definitively interested by your post jam update, tho dont overscope it, a small completed project is better than an aborted big project :)
