$10+ - [Full Version] v2.1 - Glowing Deeper

Thanks for everyone's patience while I worked on v2! This update was a huge one! I'll likely be breaking down the next few updates into smaller +0.5 chunks going forward, so we can have more consistent updates throughout the month.

Edit: Got some great feedback recently for this version and found a few scary game-breaking bugs. Please update to the newest version to enjoy the game with fewer interruptions! Also added dearly needed QoL enhancements, full list below!

[Known Bugs]

Will be updating in about a week or two, try not to eat food until then!

Left/Right Glowstones are bugged. Placing them makes them Up/Down Glowstones (unimplemented). Avoid using if possible until fixed!

Significant Saving Bug found! Do not idle on the Title screen or your Save data will become corrupted!

Making a patch to fix this today!

Trouble with swinging pickaxe on Windows (not enough info, if you encounter this please let me know)

Some cutscenes are still unfinished (new smelter/pocket/ect)

Chests on Map currently have no purpose

⭐v2 Major Features!⭐

💧Lumi the Slime

Lumi will join your adventure starting at Floor 16. She will provide Slime that you can collect from her to craft more advanced items, like Glow Stones and Gelatin.

🍄Mushroom Forest

Starting Floor 20, you'll need to smash some Mushrooms in addition to the normal Ore Rocks if you want to descend! Mushrooms have 3 different colors that spawn randomly: Green, Purple, and Red. Figure out which mushrooms you need to progress deeper into the cave!

⚫Demonic Ore

Mining at a Depleted rock for too long will eventually spawn the Demonic Ore Rock. This rock has a timer that you must destroy it for the reward: Demonic Ore. You can use Demonic Ore to smelt Demonic Ingots and create Explosion Boosters.

💎Geodes

Geodes now appear randomly in addition to Ore Rocks. They have higher durability but lower Yield. Collect as many gems as you need, but be prepared to invest some time doing so.

🧨Explosion Booster

Using a Demonic Ingot, craft an Explosion Booster that will deal a percentage of your Charged Pickaxe Power as bonus damage every 0.5s. They are difficult to obtain so make sure you use them wisely! (Explosion Boosters do no damage to Demonic Ore Rocks, and their duration timer will pause until a new rock appears)

⛏️New Pickaxes

Smelting enough Iron/Copper/Silver/Gold Ingots and Diamonds will award you a new Pickaxe cosmetic for each type. They each provide permanent bonus damage regardless of which is equipped, so collect them all! A Mushroom Pickaxe is also available which will help you with the Mushroom Forest.

🍄Consuming Food (Energized State)

There is a new tab for cooking food recipes, obtained upon reaching Floor 14 for the first time. You can cook several recipes based on what you have available, including Fish, Mushrooms, and Slime recipes. Salt is now obtainable from Ore Rocks, and a higher chance of collecting it from Geodes. Consuming 5 points of Food Energy (1 point per dish) allows you to become Energized upon opening the Food Menu again. This state lasts for 5 minutes and increases the speed of hitting rocks and reduces the time needed to charge your pickaxe. Make sure to craft some Durability Boosters!

👆Resurface Improvements

Many bugs were fixed in this version to allow you to spend and obtain Character Tokens to upgrade your Characters (Tippy and Lumi). Expect more polish in future versions as well.

Additional Improvements

Fast Travel - Select a tile to Fast Travel to and you can go straight there without opening the Map first.

Auto Save - Enable in the Settings menu

Brittle Rocks - Occasionally a 1HP rock will spawn. Destroy it in a single hit and obtain your rewards!

New Achievements and Cutscenes

Cards - Rare cards will spawn by doing everyday activities (mining, smelting, and panning). These cards will be used in future update and will persist through Resurfacing and Descending. Collect them now and use them later!

Menu UI Improvements - Upgrade Animations

About 25 new items added including the Slime, Mushroom, and Food variants

Smelting speed significantly reduced for Flakes > Ore

Increased the amount of Gold Ore Rocks and Silver Ore Rocks from Floor 10 > 19

Tippy animation for catching fish (work in progress)

New Code: Explosion1 - [1 Explosion Booster]

New Code: TippyCompensation1 - [1 Tippy Token]

🔮Future Updates [v2.5]

New Character: Mule Girl (name TBD)

Mushroom Forest background and Map

Lumi will join you in the minecart

New items and crafting recipes
