Great stuff

Linear, but I loved it.

well... for those who don't understand, you have to trace the cursor along the arrow to the library - from the bottom to the top.

But Huck Finn and Tom Sawyer are BOTH main characters in Twain's literature...

Not sure it lived up to the potential

First of all: I love these games.

But the inability to control multiple planes really diminished the experience - it would be awesome to set up a battle with a couple of fast planes and a fortress vs a wave of enemy fighters.

It also didn't really seem like you were defending anything. If enemy bombers had been doing bombing runs on ground-based targets, maybe there'd be an incentive to take them out quicker, for example...

Anyway, I realise you're just testing the waters for a large-scale Steambirds game... But this was too repetitive, and choosing multiple planes to control would have allowed for greater customisation and replayability.
