Thank you! Yeah it was a hard choice of how we should do that detection part, since we wanted no UI, because they could break the immersion you are having while you're in the dark there. For the artwork we can't take any credit though, one of my teammates GF made them, look her up on IG for great artwork: @inksmudges!
That detection part was hard, we had like a detection sound when they saw you and you still had a chance to run away and on level 2 obviously the time stop powers. I think the detection sound ("huh who's over there") ended up being a bit too quiet, so not sure if anyone heard that actually.
I love stealth games as well and it was so cool to do something like this and the learning curve that happened in a month was amazing, it was our first game jam, but for sure not the last one!
