Atmo Sphere

Post by Fiskbit » Sun Feb 28, 2021 10:30 pm

Atmo Sphere is an action-puzzle game where you control a bouncing ball. Stages are cleared by breaking all the non-death blocks and meeting score targets by chaining together blocks of the same color. The blocks advance downward every time you land on the bottom of the playfield, and lives are lost each time blocks crash into the bottom. Lives replenish after completing each stage, but lose them all and it's game over. 30 puzzles in all, available across 3 difficulties.

Controls:
- D-pad: Move the ball left or right
- Select: Restart the current stage (forfeiting a life)
- Start: Pause
- B: Double the ball's vertical speed
- A: Launch the ball / Dismiss message

Difficulties:
- Zen: For more casual play, but the later stages still get challenging! 5 lives per stage and no score targets.
- Normal (default): A good challenge. 9 lives per stage and moderate score targets. Missing a score target costs 1 life and repeats the stage.
- Hard: Requires near-optimal play on each stage and encourages clever solutions. 5 lives per stage with strict score targets, and deaths restart the current stage. Missing a score target costs 1 life and repeats the stage.

Scoring: Clearing blocks of the same color builds up a combo, with each adding 1 more point than the previous block. Switching colors restarts the combo's scoring at 1. The current combo value and color are shown in the HUD.

Block types:
Solid: Reflects the ball and contributes to combos. Available in red, blue, green, and yellow.
Arrow: Reflects the ball, contributes to combos, and immediately advances the blocks by 1 row. Available in red, blue, green, and yellow.
Nonsolid: Does not reflect the ball and doesn't change the combo value, but does add the current combo value to the score when hit. Has no color.
Death: Reflects the ball, clears combos, and counts as a death when hit. Unlike other blocks, these move safely off the bottom of the screen.

HUD:
- Lives are shown by the circle icon on the left.
- The current combo value and color are shown in the middle.
- The current and target scores are shown on the right. You can complete the stage if the current score is at least as large as the target.

Continues:
- You can continue the game at the last stage by holding up and A when starting a new game on the title screen. You can even use this to switch to a different difficulty!

Console compatibility: Atmo Sphere automatically detects whether it is running on NTSC, PAL, or Dendy systems. While gameplay is slower on PAL and Dendy systems, audio and video timing have been corrected for each region.
