I have here a couple suggestions:

- Punish tango build by reducing tango income while leaking.
- Improve king potencial, since "late game" is very hard to hold a wave with him, and there is no reason to improve him.
- Improve tooltips for sent monsters ( its very hard to choose one rn by the lack of info)
- Limit players move by its zone, since players can create towers in other player's lane
- Use the wc3 classes: it will make the process of developing the map quicker, and those classes are ready and optimized. I LOVED all of them and don't think there is any problem at all in them.

Bugs:

- Duel finishing before someone wins it, maybe because too much time has passed.
- King's tooltips missing.
- If a tower is created on the last seconds before the wave starts, it will bug and won't move.

If you want to translate the game to portuguese (wich is used by Portugal, of course, Brazil and plenty of other countries in Africa) feel free to ask me. I love this game and would love to help.

Keep with the good work ^^
