Terminal Colony Deep Core layers mining automation with worker management and tech progression in a text-based interface, but suffers from significant technical issues and poor documentation. The core loop involves digging deeper for resources while researching upgrades, though players report bugs, unintuitive UI, and confusion about core mechanics even after unlocking content. Best suited for players with tolerance for rough early-access experiences who enjoy experimenting with systems despite friction.

As someone who plays many diamonds in the rough I tend to have a good amount of patience for weirdness/unpolishedness. This game is beyond that. Plenty of bugs, I can't figure how to stop the screen from flashing when clicking, no upgrade menus but floatable windows which get in the way. Progressing and unlocking achievements while I still haven't even started figuring out how things work.
v1.4 is a major update that improves both the game and the codebase.The biggest change is a full upgrade to Bevy 0.18. On the gameplay side, the new Prestige Shop adds permanent Quantum Point upgrades that carry across resets, including progression boosts and starter resource upgrades.This version also adds resource fly-to-UI animations, making mining feel more responsive and satisfying, and fixes several important prestige/reset bugs (including resource carryover, achievement re-unlocks, and requirement calculation issues).Under the hood, there are also code quality improvements, stronger persistence testing, and full localization support across 19 languages.Overall: v1.4 is a polished, stable milestone release with better progression, better feedback, and a modernized engine foundation. Thank you for the support and playing.
After a few attempts, I finally got the game migrated to Bevy 0.18. Some colors and a few Egui elements were off after the update, so it took me a while to track everything down and fix it.I also added a Prestige Shop this was a player request, and I liked the idea, so I built it directly into the prestige Egui.Thanks for the support, and thanks for playing! New FeaturesResource fly to UI animation Mining now has clear visual feedback. When you collect resources, small icon tokens appear where the action happens and smoothly fly toward the correct resource counter in the top panel.What it doesTokens travel along a smooth arc with an ease-in-out-cubic feel, plus a subtle parabolic lift (sin-based vertical offset) so the motion looks natural.The destination updates every frame, so tokens keep tracking the right resource label even if the UI shifts or the layout changes.Built to stay lightweight: up to 15 tokens at once, with throttling so each resource type can only spawn one token every 0.5s to avoid spam.Supports ore, blocks, crystals, energy, uranium, dark matter, and quantum bits.When it triggersOn player clicks for ore and blocks.On block destruction for all resource types.
SummaryTerminal Colony: Deep Core v1.3.6 is a hotfix and balance update focused on consistency and persistence. It resolves a long-standing issue where click power could differ depending on whether it was rebuilt after a prestige reset or after loading a save, sometimes resulting in large and unexpected changes. The update also tightens prestige rules by scoping achievement bonuses to the current prestige run, preventing bonuses from stacking across multiple runs.This release improves reliability of language and display settings by ensuring they always persist to the preferences file and are no longer overwritten by older save data. Several UI and display issues were corrected, and late-game economy pacing was adjusted through targeted cost increases. All saves from v1.1.6 and later remain fully compatible with no migration required.Release Notes v1.3.6 (2026-02-08)HighlightsFixed click power inconsistencies across prestige resets and save reloads by using a single canonical rebuild path.Achievement bonuses are now scoped per prestige run to prevent stacking across runs.Language and display settings now reliably persist through menu changes, in-game changes, and exits.Balance adjustments: plasma offers +30%, Crystal Detection cost increased to 80 crystals.Bug FixesClick Power Consistency (Prestige vs Reload)Resolved a divergence where click power could be rebuilt differently depending on whether the player prestiged or reloaded.Both prestige reset and post-load recalculation now use the same rebuild logic.Click power is rebuilt from: prestige level, claimed achievements, researched tech, and purchased upgrades.Prevents unexpected jumps or drops after restarting.Achievement Bonuses Now Reset Per Prestige RunAchievement progression is cleared on quantum reset.Click power and global bonuses now apply only from achievements earned in the current prestige run.Prevents unintended long-term stacking from prior runs.Prestige UI CleanupRemoved a duplicate “full reset” action...
