Oh my god.
Dude, your games are killing me, and everyone that plays them. Stop making them.
Making them? No... wait... thats wrong...
The right idiomatism, is "stop stealing them and then telling that you are developing them".
Needs a delete button, for each element, for example: i have acid in level, but its between many other things! I dont want to destroy the other! Only the acid! So i press delete button for acid and acid is gone.
@onimatrix: That (obsidian), and acid with virus should be also stoppable. Especially acid. Why the ground melts with acid? lol.
Between, are you a teacher in physic or chemistry ?
From the part that mother said something about a plan, I knew that something was wrong. And at the end, before the escape, when she repeatedly was saying "You killed me" it was scary in a different way than we know, and the message in the end was bit of strange. And the phrase "Stay where you are, you do not deserve to escape" was kind of melodramatic. It wasnt a good game, but not a bad game either, so I'll give it a 3/5.
Ive created a triple enviroment, filled in one side with lake and fish, other side ground and ants, and middle, a giant volcano. And all, in same box. 5/5.
