Thank you!
I think maybe I could have both, I could add a casual mode that turns off the timer, or just make the timer only impact the score obtained rather than forcing the player to finish within a set time. Set times are difficult anyway as one persons "fast" is different from another persons "fast", that and the puzzle would be more accessible to many more different players.
Mini map seems interesting though not sure I have enough pixels for one if I stay within this limits of this Jam. I could maybe at least show a "mini map" of the truck maybe, or do as another person suggested and make more of the area visible, though I'd need to redo all of my tiles. Not sure on this one.
As for the sound, thank you, was just messing around with making my own sounds with my mic, that particular sound is from a device you use to measure your blood oxygen (oximeter) and it's just the noise if me letting it close down quickly without my finger in it. LOL I really wanted to make some more Gameboy sounds, but ran out of time so needed to throw some sounds in to at least add some experience with that aspect of game making.
