My teenage sons have just had a few rounds, here are some of their suggestions...

Rounds to be timed - in case someone is AFK

Single player mode with difficulties

Easter eggs...?

Upgrades for weapons

Larger variety of maps

2 v 2

Armour, shields

Both would play Panzer Pandas on their phones if there were more options and levels.

Your welcome, with 4 in a row, I played a piece first my hubby could not get anything to work, there was no error message, his board did not light up when you ran the cursor over it - clicking anywhere didn't work either, he uses Firefox.

In Panzer Pandas (not sure if this is due to lag) my sons play screen showed a different picture to mine, my pandas would be surrounded by the dirt whereas on his screen it would show a massive hole where the missile had hit and vice versa.

In another game my son fired a purple missile hitting both targets and knocking both pandas to 20% health, when it was his turn again the game reset to full health but the missile was missing...

A description on what the weapons do and how much damage they deal would also help.
