Laboratory Madness

It is a fun story about a scientist trying to make up some inventions. The inventions and the way how to (randomly) find them is entertaining enough. Unfortunately there is no handling of choices which already have been made, so they can be repeated over and over again; it would have been better to take them away from the list of choices after they have been chosen, because the gameplay gets confusing when the player decides to chose them for a second time and the result is just the same.
(Spoiler - click to show)The occurence of time travels does not explain this, because this aspect aims at different parts of the story.
A negative thing is that I did not find an ending... or maybe I missed it?
The basic premise is not bad though, and maybe this could be improved in a later version one day.
