Very solid, fun game with legitimate replay value. That being said, the game is too easy. Find a barbarian, go berserk, fall, repeat. Wait around if your mana runs out. Even without a barbarian, the game wasn't overly difficult unless I was aiming for artifacts. I'd suggest adding a necessary gold requirement to get a key/princess and having an even higher gold requirement for the artifact/life.
Two other additions... Let us replay a level until the artifact was obtained and halve the number of heroes but double (or quadruple) their gold value. This (along with adding a gold requirement to get a key/princess) would force players to switch it up, rather than riding down as just one hero.
Whoever says that this game is a grind or takes too long, you aren't playing it right. Get pole vault and up n out. When you hit the ground, use pole vault, then flip followed by up n out twice, then pole vault again, flip again, followed by up n outs, etc. You can combo them together to easily get x10 on a huge trick and make 50k-100k per jump
The game is too easy, I beat the entire thing in 15 minutes.
The trick is to out produce your opponent. Focus on the small ones first, the big ones don't produce that much faster. Also, in the middle of the battle, it is better to steal from the computer than it is to take a nuetral one.
