I ditched the retro keyboard based inventory screen in favor of a mouse based one. It makes the game flow a bit better, I think, and now items are sorted by tabs! I'm probably going to add a favorites tab eventually, so you can keep track of the important items you use a lot.
Oh and ladders are in the game now! Very important for climbing vertically, and making a nice base. Trampolines only cut it so far.
Next I'm going to finish reworking the UI, and then add upgrading items into the game. Not sure how I'm going to handle upgrades quite yet; as having everything being upgradable would be silly(Who wants a level ten paint can!?) but on the flip side of that, who am I to tell you how to play your game?
