Confusing and frustrating
You get power ups that sometimes mean nothing to me like, 1% growth ? Is it meant to give me more powerful power ups or gain more XP or money... Is the character going to get bigger? No idea..
And you probably have to okay is about 30 times before you get a decent amount of upgrades to allow you play a bit better, but still quite frustrating.
And what are the train and the boat for? You can't get to them and there's bonus left on the water to be collected, which you can't get to.
Is there any objective apart from running around and dying when monsters simply won't die anymore?
And how about a main menu where you can get these instructions/info from?
Perhaps add some places the player can go to and allow us to keep the partners we collect, otherwise it is an impossible game.
