Hi
Thanks for trying it out, the drop button is bit redundant I think I will remove it in the next version and change the message about carrying stuff. By design you can only have 5 items in your inventory otherwise the game is a bit to easy and forces you to go back to the store for more consumable supplies. Once you have brought an hardware item there isn't any way to get rid of it currently (maybe could sell it back to the store in a future version).
Your input has helped me realise it need to redesign the control scheme to make things clearer.
Graphics where fun to make glad you liked them.
