The game was badly designed.
When the player is with full energy his attacks are almost useless.
The attacks in general were very slow to recharge leaving no satisfaction.
In the biggest form the player is unable to jump one tile upwards and this leads to a dead end, the sword attack also do not reach far enough to give the ability to attack an enemy in this form.
The shooting height changed in every size turning the shooting almost useless.
I am sorry, but this was a bad game.
