We liked many of the mechanics, such as the fact that they duplicate when they fail or that you have to select the right weapon. We also liked that the numbers assigned to the monsters change and that you can clearly see when this happens with the text effect. The monsters are cool and have been a hit with our kids. As a suggestion, we were thinking about weapons x2, x3, x4. All x4 monsters could also be killed with x2, so we wondered what would happen if they were x2, x3, x5, but these situations would also occur. We have experienced that after playing for a while, the browser restarts the page indicating that it has used too much memory.
