Thanks! Yeah the jump is jank, but I kinda liked the effect when you can jump super high.
For now, the inventory is only really used for the gloves and the pickaxe, but there will be more things to scavenge etc. once i finish designing and implementing more game mechanics. And yea, only the "front" of the sprites is drawn, but it would be simple to draw both sides I think.
I want to add NPCs at some point too but I have to make sure it fits with the rest of the game mechanics.
