Despite it's big flaws, this is a game that deserves a solid 5/5 from me. However, as everyone mentioned, in the sequel, pause button, destroy before startup, and maybe better shield modules (more expensive is ok).
Good but one problem is it's way too easy and the cheaper units are just decoration. In the end you just fortress spam and line up anti tank guns behind it. Reinforcements are pretty useless.
Too easy. Start off on easiest setting, puny town. When you're about to win and damn overpowered, train up 5 folks to max in everything (10 in all 5 stats). Then, fly off to new town, seriously hard difficulty, and puny town. Should be a piece of cake.
guide to 50k - the "normal grindy" way. You need 16k in total score for this, of which estimated 14k from stunts.
Golden cart + hangglider. Get perfect, then 4x multiplier.
superman+up and out + flip + spam handstand till it's turning blue (reentering atmosphere). Should sit at at least 3, likely higher now.
pop hang glider, superman + upandout + upandout flip + spam handstand keep on spamming.
Now, should sit at about 8-10k if done right.
Once hang glider disappears, don't do anytihng just brace for impact. When you're headed down, start polestanding. You should only need to polestand 3 or 4 times. Once you hit 16k score, just land yourself gently.
Rather painful to get, the hardest part is the polestands. Practice without anyone on board till you can do 6 polestands in a row. Then go for it, but will still take a few tries.

You don't need to pay for the badgets. Boths badgets (heroic and Iron) are for no premiums levels.
