Thanks for playing! Out of curiosity, what browser/system are you on? I'm still relatively new to trying to make stuff work nicely in a browser and trying to triangulate the source of the issues a few people seem to be having. One person found that the game was laggy for them in Firefox but not in other browsers, so I'm wondering if there's an issue with the browser being used or something. I hadn't considered that the browser could be the problem, and being a big dummy I only tested the game in Vivaldi, which isn't exactly a common web browser choice hahahhaha. "Oopsie-Froggie" (that was my favorite voice line to record hahahhahahaha)
So the flashlight is most obviously used to light up the play area, but less clear is that it signals which frog has a key in each wave. My thinking was that by shining a light through something like a frog, you can (probably? I imagined this without testing it on a real frog haha) see through the frog and see what's inside it and stuff, kinda like when you shine a light through your hand. So the idea is that if you're quick enough you can always use the flashlight to find a key in each group of frogs. I did feel like the game eventually lost the plot of the theme of the jam, but my original concept was about signaling game mechanics to the player in an atypical way (I hand drew the keys into normal map textures so there's no magic shader or texture swap happening to make the flashlight-signals-key thing work, it's all just baked into the lighting system). It was really fun to build and I think it looks pretty cool (if subtle) even if it didn't end up being the centerpiece of the game that I expected it to be.
