Nice! Having both the speed and inventory upgrades was a really nice touch to make this enjoyable and doable! to be honest the speed might feel a little overpowered after a few upgrades, but still its a fun concept and well done!
Thanks!
It's always difficult to balance a game, so I tried to make sure it wasn't too hard, but maybe it's too simple now, I don't know.
Honestly its fine, I loved zooming around the map once I had upgraded enough!
