📢 Battle Titan: RAINBOW – Exhibition Report & Development Update
Hello, this is the developer of Battle Titan: RAINBOW (BTR).
Reason for Delayed Updates
In December, I participated in two consecutive indie game events in Korea.
As a solo, part-time developer, I focused on booth operation, bug fixing, and exhibition preparation,
which delayed development updates.
Recently, BTR was showcased at two small indie game exhibitions, where the game was presented to both user groups and the general public. During the exhibitions, the game did not freeze or stop, though several bugs were discovered and are currently being fixed.
Notably, Steam Deck performance proved to be very stable.
Exhibitions
Korea Indie Game Showcase
Small indie event held in Pan-gyo City
35 games, 3-day exhibition
Feedback-focused sessions with user groups
Beaver Rocks 2025
Indie exhibition hosted by [Smile Gate]
Held annually since 2022 with a high selection bar
85 selected indie titles
Strong exposure to general audiences
Intro scenes were shown on a large screen
Exhibition Results
Arcade mode fully playable from Stage 5 to Ending
One crash during 24 hours of Steam Deck play (not caused by the game)
CPU ~35%, GPU ~40% usage, stable 60 FPS
Player skill levels ranged widely from Easy to Hyper
→ Three difficulty levels planned
Strong positive response from the target audience
→ The game has reached commercial-quality vertical slice level
Key Feedback
This game is not casual or all-ages (by design)
Boss battles received the most feedback
Difficulty perception varied greatly
Many experienced players requested very high-difficulty boss fights
The mixed vertical/horizontal STG rule set was well received
Going Forward
Operating the booth alone as a solo developer was exhausting and required recovery time.
However, positive feedback from the core target audience removed my remaining doubts.
Development has now entered the phase of final content production and repeated testing,
with a planned release in late 2026.
I’m sorry for the long wait, but at this stage, compromise is no longer an option.
Thank you for your patience, and I wish you a wonderful end of the year.
