This is tough to review because it's great that the puzzles are hard, but too many are absurdly difficult; wherein the solution is something no rational person would ever come up with, and some puzzles simply are WRONG and could never be solved without the instructions. One I just did gave a hint with colors on a circle and if a color is on the right side, you press the right button on a drawer and if on the left of the circle, you press left. THE SAME COLOR WAS ON BOTH SIDES!!! The solution showed the order to press (e.g LRRL) but there was no correlation between the clue and the solution. I've found a few games by this programmer that have impossible (or wrong) solutions and it's infuriating. You will NOT be able to do all the rooms without buying clues and the clues are expensive and misleading. For $2.99 it says you get "10 rooms" of clues (around $1.99 for 3 rooms & $2.99 for 5 or something). You DON'T get 10 ROOMS of answers, you get 10 ANSWERS! If there are three puzzles in a room, that's it... you used three solutions out of 10. So you could spend $4 to solve two or three rooms! That's ridiculous! Especially since many of the puzzles are so absurdly hard you have no choice but to use them. To get a few good brain-teasers per game with some being just insolvable isn't worth the investment in time & money. Lastly, most "escape the room" games have more items to be picked up and interacted with other pieces to solve puzzles. Lots of stuff to click and do. The games from this dev have maybe one item per room to pick up and the rest is trying to solve over-complicated, static puzzles. While that's not necessarily bad, it's worth knowing if you're looking for the typical escape game. This ain't it.
