There is something quite satisfying about skipping full speed rounds! however I found myself clicking the mouse to upgrade my troops constantly, I would have loved to see a button to use all your money into one troop or perhaps big amounts of money. For example spend in upgrades from 1000 to 1000, so if the upgrades is 987, it pays it but if it goes over 1000 it doesn't. Anyway good job on the game and the different troops design
