Sorry to hear it wasn't fun to play. The hint system is not the best at the moment. I am working on a new update which includes a proper tutorial, better hints + controls on the screen etc. I am trying to get it finished soon, it's just taking some time to complete. I would wait for that if you ever want to try the game again.
To use item you put in the toolbar, you press either 1 or 2 depending on what slot you put it in. Controls are changeable in the options. Planks can be crafted from logs while in your inventory. You hover over an item and you should see the possibility to craft a plank.
