Great game! Especially great since its your first proper game jam game. I read the other comments so while the timer going negative makes sense now, since the timer is bonus points I would instead label it as such, because while playing it felt like a glitch, like I was supposed to have lost the game. Also, I think your characters movement is not normalized though I could be wrong but it felt like I was moving faster when moving in the diagonal direction, which not bad is something to look at in the future!
