The game's code is currently at .85 version with still significant development needed
The game design evolved from generic haunted house concept to B-movie themed after acquiring movie licensing
Six main B-movies are featured as primary haunt modes in the game
The game includes three sequential multiballs tied to different movie groupings
Lyman Sheets has been wanting to design a haunted house themed pinball game for a long time before this project
The B-movie theme concept emerged after discovering the public domain film compilation, significantly changing the initial design direction
Modes are presented in linear order during the reveal stream for demonstration clarity, but will be randomized/selectable when the game ships
Mode timers reset on successful shot hits, allowing open-ended gameplay where players can continue as long as they hit shots within the timer window
Lyman Sheets designed the code for Elvira's House of Horrors
Lyman Sheets worked 36-48 hours straight during the initial six-week push to complete Tommy
The blind modes feature on Tommy (where players cannot see flippers) was a first-time innovation in pinball at the time
Current pinball industry has returned to or is within the golden age that existed in the 1980s-early 1990s
Tommy game's mode timing out mechanics were by design to allow concurrent modes rather than forcing sequential completion
Lyman Sheets provided improved code versions of Tommy to Lonnie Ropp and another friend Dallas after leaving Data East

Batman 66's LCD mini-display system was designed to help players track scoring sources during multiball play
Batman '66 v1.0 contains essentially all major features Lyman Sheets wanted in the game from the beginning, though more content is still planned for future updates.
Studio games at Stern (like Batman '66) have no fixed production deadline, unlike cornerstone games which follow a scheduled roadmap.
Modern Spike 2 hardware has essentially no storage or memory constraints, eliminating limitations that plagued older pinball code development.
The major/minor villain system in Batman '66 was designed to serve both casual players (major villains) and advanced players (minor villain stacking strategies).
Batman '66 features three distinct wizard modes, one for each TV season, selectable after completing villains from each season.
AC/DC (Premium) balance issue involving cannon mechanic was discovered in tournament play by Bowen Kerins and required developer adjustments.
Typical pinball designers get 'one chance' to design a game, with Star Wars being exceptional in allowing multiple design iterations.
Lyman Sheets scored only 2 points out of 12 possible on EM games at Pinburgh 2018
I worked at Data East starting as a display programmer, then at Williams as a game programmer, then Midway Games making video games from 2000-2003, and now I work for Stern.
Roger Sharp told me 'if I do it a second time, just make it worth more' which became foundational to my scoring philosophy throughout my career.
I was originally a support programmer on Congo at Williams, but was pulled off to work with Brian Eddy on Attack from Mars because Congo was being redesigned.
Slash from Guns N' Roses came into the Data East engineering facility multiple times during game development and requested Jack Daniels during meetings.
Attack from Mars' billion-point Total Annihilation hurry-up start is the most fulfilling moment in pinball for me.
I had approximately 20 tournament wins across my competitive career, with roughly 5 being major championships.
Working at Midway Games was less creatively fulfilling than pinball because programmers implemented designs rather than contributing creative ideas.
Medieval Madness and Attack from Mars remakes were valuable because the industry recognized these designs were 'decent games' that didn't need major changes.

Lyman and friend Mike Teixeira won IFPA doubles tournament in 1992
DataEast Tommy prototype had six bumpers, a shaker motor, and chiming effects that were removed in production
Tommy was developed in just six weeks to premiere games at Dallas stop of Broadway musical touring production
DataEast's system architecture was essentially Williams System 11 with added dot matrix display capability running on separate 6809 processor
Dual-CPU architecture with separate display processor created synchronization challenges that would be easier with single unified processor
Early internet/Usenet (1990s) was more helpful and had higher-quality discussions due to smaller, more educated userbase
Lyman did not spend excessive hours practicing to achieve tournament success, contrary to common assumption
Production version of Tommy plays significantly better than prototype version despite prototype having more features
