Even when you're fully upgraded, you can still buy the highest level stuff again and again. Also, if you just get a good battery, decent drill, and full cooling, you can just dig straight down to the core ore.
Something that REALLY needs to be fixed: When I put the game on fast forward to speed up a battle or to get my money faster, the dialog boxes that pop up to say that humans have re-conquered a city or whatever else immediately disappear. Please fix! (+ so he sees?)
I find myself falling through platforms far too much with the first spring upgrade to give this any rating above 2. Please fix this bug, then I might be more inclined to rate higher.
Decent game, but it really isn't as fun as the others. The mini games here are more tedious than fun, and since doing mini games over and over again is basically the point of the game, that's a pretty big deal. I can't give this anything higher than a 3/5.
I'd like it if we could aim where our Spike Factories put their spikes, similar to the Mortar towers. I hate it when my Spike Factory keeps putting spikes off of the track and letting Bloons through.
It doesn't seem like the bottom-right most achievement works, my total score (over all games) is well over 400k and I haven't gotten the achievement. Either re-word the achievement, or make it work with the total score over all battles.
Why does EVERYONE complain about me not having a certain thing, especially since I only JUST unlocked it? It's just ridiculous. Not everyone who visits a hotel is there to use the stinkin' Gym!
Someone should make a zombie apocalypse game set in Madagascar. There'd just be one button that says "Close all airports, borders, and docks". Clicking it would cause you to win the game. :D
Tip: The larger bikes (wheels farther apart) such as Gregatar are more stable, thus easier to ride, but slower to spin, thus harder to get points from wheelies and flips. The small bikes (such as Gregatron and The Big G) are the opposite; hard to keep stable, but easy to spin so you can get more combos. Bikes that are somewhere in the middle, such as Gregzilla, are probably the best choice.
I saw "Trouble pressing the Play button?" at the bottom of the first screen, and expected the next sentence to say "You may be too stupid to play this game." I was disappointed.
