Retro Game Coders’ 11th installment adds five levels to its Commodore 64 BASIC dungeon crawler. Players must collect every chalice on a level before using the stairs, while their character carries health, stats, gold, keys and magic forward.
Retro Game Coders’ Part 11 adds a five-level progression system to its Commodore 64 BASIC dungeon crawler, replacing the earlier single-map structure. Players must collect every chalice on each level to unlock its stairs, while their living character carries health and other stats into the next map.
Each level uses the map generator introduced in Part 10, with additional rules for placing objects and stairs. The number of chalices required rises across the five levels: one on levels 1 and 2, two on levels 3 and 4, and three on level 5. Chalices continue to be worth 10 gold each. Once the last one is collected, the message log directs the player to find the stairs.
The stairs are placed in a randomly selected corner room, away from the central starting room. Entering them before collecting all the chalices sends the player back and displays how many remain. After the final level, the stairs end the game with a win; the end screen now also reports the level reached and gold acquired.
The code separates starting a character from generating a level. Character setup runs once at the start of a game, while the level-building routine runs again for each map. That distinction lets a living character retain hit points, stats, gold, keys and magic when descending, rather than being reset with every new map. The tutorial says level completion also restores hit points based on constitution and raises strength or dexterity, alternating by level.
A Run Now Spans Five Maps
The update changes the project from a one-map game into a short dungeon run with a recurring objective and rewards between stages. Players must explore each map for every chalice before they can leave, making the stairs a progression gate rather than a simple exit. Carrying a character forward gives accumulated health, equipment-related resources and stats a role across more than one encounter.
For readers following the coding series, the change also shows how a game can distinguish between resetting a level and restarting a run. The author divides those tasks into separate routines, so new maps can be built without discarding the player’s character. That structure is relevant beyond this specific crawler: it provides a practical foundation for adding further floors, challenges or progression rules later.
The author describes the stat increases as an initial demonstration rather than a balanced design. The actual value of those bonuses will depend on later game systems and testing, so the update establishes a progression mechanism without claiming that its rewards are final.

From One Map to Multiple Levels
In the preceding installment, the crawler had a playable single map. Finding its chalice ended the game, and choosing to play again created a new character and map. Part 11 builds on the map-generation and room-connectivity work from Part 10, reusing the generator while adding level-specific object placement.
The tutorial is part of a step-by-step C64 BASIC project. The author says readers can follow and edit the code in an online retro IDE without downloading or configuring software. The current five-level structure is a new stage in the project, not a report of a commercial game release or a completed, independently reviewed product.
“In this version we move to have five levels.”

Balance and Placement Limits Remain
The installment does not describe playtesting results or establish whether the current health and stat bonuses are balanced. The author explicitly says those rewards may be reconsidered during a later polishing phase. It is also unclear from the source when another installment or a finished version of the game will be released.
There is a stated limitation in chalice placement: the placement routine stops after 200 unsuccessful attempts to find an empty floor cell. A chalice may therefore fail to appear on a crowded map. The code counts only chalices successfully placed, which, according to the tutorial, allows the player to complete that level using the chalices that did appear. The report does not give test results showing how often this can happen.
Further Tuning Is Still Planned
The immediate next step described by the author is not a dated release milestone. Instead, the tutorial leaves room for a later polishing phase, when the usefulness and balance of character bonuses can receive more attention. The five-level run currently ends after the player clears level 5 and reaches its stairs.
Readers can follow the project through the Retro Game Coders tutorial and try the code in the online retro IDE, as the author describes. Any further features, changes to level design or adjustments to rewards remain unconfirmed in the supplied report.
Key Questions
What changed in Part 11 of the C64 BASIC dungeon crawler?
It adds five levels, chalice-gated stairs, character persistence between maps and stat rewards for advancing.
How many chalices must players collect?
The levels require one chalice on levels 1 and 2, two on levels 3 and 4, and three on level 5. Players must collect all chalices that were placed before using the stairs.
What carries over when a player descends?
A living character keeps hit points, stats, gold, keys and magic. The game builds a new level without running the character setup routine again.
How does the game end?
Reaching the stairs on level 5 after collecting the required chalices wins the game. The end panel reports the gold acquired and the level reached.
Are the level-up rewards final?
No. The author says the current health and strength-or-dexterity increases demonstrate how progression can work, and that their benefits may be reconsidered during a later polishing phase.
