Bug/Issue Found a pretty useful albeit unintended bug

Two tech upgrades can create an unintended side effect. If you use spike sphere and wall jump together, you can end up being to roll around in ball form while still being able to use items (you will still run out of energy and end up staying at zero energy if you use something that requires energy). All you have to do is jump on a wall so your character is rubbing against it, then switch to ball mode. It's very useful for creating a mineshaft, as you can dig and place blocks as you descend/ascend.
