Thanks for the gameplay video. I hope y'all had a lot of fun making it. I think something that might help is increasing visibility (hopefully you can still keep the mood), slightly decreasing difficulty (if its too hard for the developer its impossible for the player), and possibly doing something to make success more rewarding (Checkpoints maybe? Or an item that helps you regain progress faster?). Great work this jam! Good luck in future endeavors!
Hello, I am the level designer. Thank you for playing our game and giving all this feedback. We had fun making the game but we had only 1 day because we were busy the rest of the time which did put a lot of pressure. The game indeed needs to be brighter. I guess I didn't notice because my monitor's brightness is too high :/. This is a shame because this leads to some people having a bad experience. We were going to add brightness slider but we ran out of time. About the difficulty, Vulpes did say multiple times that it was really hard and I tried to make it easier but I couldn't test it myself because it was not hard for me and he was busy but if we continue working on this project I will definitely try to make it easier at least at the start.
