Add more towers and enemy please
Love the game
It would be nice to add new guns upgrade that change the picture! ex. Gunshot would be changed to Multi-shot, like Shot gun but Multi-shot is a better name if already is called Gunshot, also maybe you can add a boss that have a ton of health more than rockster! and I would like to see a new update about tickets, i see a lot of it in other games, so basically(just realized i spelled basically right the first time) you earn like 1m and get a new ticket or like %200 of earning per hour or so, and I know that you are very unproductive but thats okay, it will come out in the least moment you even realized!
Teleport. A 'From' and a 'To' so it takes up two squares on the map. It needs to be ridiculously expensive - something for when the map is getting full of weapons. It must be ridiculously slow to reload, much slower than a Rockster navigating the entire map.
The idea is one puts the 'From' base in the last square and the 'To' in the first square and any monster that occasionally make it to the end gets sent back to the start.
Catapult. Sends the monster backwards a small distance - a fraction of a square. Can be upgraded to increase the distance in small amounts. Takes up a square on the path.
Similar in effect to the Stun function but without slowing the monster, but gives one something else to play with.
Perhaps: the amount it sends the monster back depends on the speed of the monster.
