Me and my teen daughter thoroughly enjoyed the rollercoaster it was to figure out each connecting puzzle! It was reasonably challenging, stimulating and kept us entertained. We played both games, solved in about an hour each and we want moreeeeee! Please! The hidden clues where more fun to find than just having the option to reveal a hint but both much appreciated. The story line, the graphics, the setting, everything! Great job creators! If you haven’t already…Get into it! ### 5/5 — Great puzzle game *2024-10-20* These devs make fun games ### 4/5 — Girl *2024-09-27* fun game however had issues while playing, the person that chose the girl character kept getting left behind ### 3/5 — Bugs *2024-09-03, version 0.3.0* The puzzles aren’t hard BUT THE BUGS MADE IT IMPOSSIBLE Great game tho ### 5/5 — Absolutely love it *2024-08-23* So good. I hope this one is longer than the rest, but my fiancée and I LOVE THEM. they help long distance 🙂‍↕️🥲 ### 1/5 — absolutely outrageous disgusting game *2024-08-21, version 0.3.0* This game is a straight up scam. Me and my friend have had numerous attempts however the game simply does not work. The final device level is not possible. We have watched multiple tutorials and step by step instructions however, it keeps saying we have not completed the level fully. This is simply not true though as I have watched how to complete on youtube. We always make it to the same level and then we brutally were refused to move forwards in our progress. Thsi game is a scam, it’s unfair and by the time this review is sent I will have deleted the game. Straight up scam, do not recommend. Me and my friends have lost countless nights of sleep over this game. It has caused me great anxiety and depression. Absolutely outrageous game. ## Frequently asked questions about Parallel Experiment Lite ### What is Parallel Experiment Lite?
