What the developers have to say:

Why Early Access?

“Tenvader is a roguelike block-building shooter where systems evolve as players progress through looping stages. Early Access allows us to gather feedback on balance, pacing, and build diversity to ensure the game's complexity grows in the right direction.

We want to involve players in shaping the experience — especially in tuning skills, block synergy, and loop modifiers. Community feedback will directly influence new features, enemy types, and special stages.”

Approximately how long will this game be in Early Access?

“We plan to stay in Early Access for 3–6 months, depending on player feedback and development pace. Our roadmap includes polishing the full loop system, adding more block skills, weapons, expanding enemy variety, and enhancing lore integration.”

How is the full version planned to differ from the Early Access version?

“The full version would have the same amount of gameplay but with more polished systems, visuals, and gameplay. Based on feedback, we aim to expand the arsenal of weapons, skills, and corrupted mechanics — along with new events to challenge experienced players.”

What is the current state of the Early Access version?

“The current version includes:
- Core gameplay loop with 3–5 bosses depending on progression
- Fully working block and reward system
- Block stat progression and unlockable weapon skills
- Penalty system, elite enemies, and special stage mechanics
- Basic sound and music, tutorial, settings, and in-game GUI
- Playable from start to end of the game, with support for replays and multiple builds”

Will the game be priced differently during and after Early Access?

“Yes. We plan to increase the price slightly after Early Access to reflect added content and polish. Buying early supports development and helps shape the game's future.”

How are you planning on involving the Community in your development process?

“We'll actively gather feedback on balance, block clarity, pacing, and skill synergy through Steam forums and our Discord server.
Players can suggest new block types, vote on feature priorities, and participate in seasonal events or challenge modes.”

About This Game

Build. Dodge. Loop. Something’s coming.

🛸 About This Game

Tenvader is a roguelike arcade shooter where you merge strange blocks to power up your ship and face waves of evolving enemies. Survive long enough, and the universe starts to break — time loops, enemies mutate, and a cosmic force begins to interfere.

Every block you place changes the way you play. Build smart. Fight hard. Try to remember what’s real.

🔷 Core Features

🧱 Merge blocks to evolve your ship
Collect and place block-shaped upgrades on your ship to boost stats, unlock weapons, or trigger powerful effects. Stack the same type of block to grow stronger — or fall apart trying.

🎯 Bullet hell meets puzzle building
Move fast and think faster. Each round combines arcade dodging with quickfire building decisions.

⏳ Time pressure with real consequences
After every wave, you get a block reward — but only if you finish in time. Fail, and the void may punish you with broken or cursed blocks.

🌀 Procedural loops, persistent tension
As you dive deeper into the game’s loops, enemies become more unpredictable, boss fights twist, and the mysterious Overseer begins to watch your every move.

💥 Unique boss encounters
Each boss introduces new mechanics and challenges. In higher loops, they gain new abilities — pushing you to rethink your builds and tactics.

👁️ Lore hidden in fragments
Discover strange messages, events, and stage effects hinting at a larger mystery behind the loop. Who broke the cycle — and can you fix it?

✨ Tenvader offers:

  • A fresh blend of Tetris-style merging and arcade shooting

  • A loop-based progression system with growing difficulty and surprise modifiers

  • Dozens of unique block types with synergies and side effects

  • Unlockable weapons tied directly to how you build

  • Hand-crafted pixel art with a cosmic, glitchy vibe

  • A mysterious narrative that unfolds over multiple runs

🌌 From the world of Rikerat

Tenvader is part of a larger universe of strange, beautiful games by Rikerat — where nothing is stable, time is a circle, and even your ship might not survive the truth.

Are you ready to enter the loop?
