So many bad points
First for 2.99 it's not bad...but..annoying points...
1. the music, even though there's an option in menu for turning music off or down it doesn't affect the music that plays during all the long cut-scenes and while waiting to start the level..also it seems to have a mind of its own and turn itself on while you're playing levels..
2. It could have been a really good game if someone somewhere had paid attention to their programming...all levels apart from 2 or 3 per hotel at the end are impossible to get expert level on whilst nearly all the levels in the last hotel from the 'chain' are possible to do this...
3. the upgrades, learning and shop interfaces are confusing and well thought out..the choice for what you can buy learn seems arbitrary at best and mostly bears no relation to what can actually help you achieve the goal or expert goal for a level...at the end of the day getting your goal is the purpose and if you can't do that because you can't choose the upgrades that will enable you to get enough customers do to so is just frustrating
All in all, it's a bit of a slog, messy, confusing, poorly thought out and the graphics are pretty naff but for under $3 you can't complain too much
