Hi maaddog,
First of all, we would like you to know that we value each and every suggestion made not only for Tower Mogul but for all our products. So do not hesitate to post your suggestions and feedback whether they maybe negative or positive.
About your concerns, I will try to explain our side one by one.
1. The left hand menu bar arrow buttons will be addressed on the next version -- this is a minor UI revision.
2. As you can see, creating a game without mouse overs is quite difficult and Tower Mogul will surely have a lot of UI issues based on every player's perspective. The reason we did not "highlight" a selected tool icon is because we felt that the text on the status bar is enough info to indicate what tool is currently selected. However, we are not closing this option because you have a valid point and we'll see what we can do.
3. That is a nice suggestion but once you get the feel of how the menu bar expands (as this was shown on the tutorial), we also felt that it was a minor issue. We'll also see what we can do on the next version.
4. May I know what device are you using? The sound volume is supposedly "universal" so it works both for the music and sound effects as what we have tested on our end.
5. This is a nice suggestion but then again, we have other implications like what if the game grid is disabled?
6. As for giving out instructions as to how each unit can be placed and constructed, we will expound on this more on the online manual because some people find this complicated and some find it easier. There is no better compromise than having a documentation available to all players.

We hope you understand. Watch out for it in a day or two. We're just doing the finishing touches.
I hope this clears much of your concerns. We are trying to make the game better each day so we hope you can bear with us. It's almost impossible to make everybody happy because some suggestions are obviously just a user preference and we are taking each step as we get there. If there is anything you need addressed ASAP, you can also drop me an email personally at
erick@esoftinteractive.com or
support@esoftinteractive.com.
Again, thank you very much for playing Tower Mogul.
Regards,
Erick
