Tower Stack
by Nebulark Studio · Casual · v1.1.0
Drop sliding glass slabs onto a tower high above a tiny twilight city. Slice off the overhang, land perfect drops for combos, and build as high as you can.
How to play
- Drop each sliding slab onto the tower; miss it completely and the tower topples.
- Pick Classic or Rush and press Play. Press Space, ↓, S, click or tap anywhere to drop the slab.
- Any part that overhangs the slab below is sliced off; the rest becomes the new top.
- Line the slab up exactly for a PERFECT drop. Five perfects in a row grow the slab back a little.
- Score = floors stacked + a bonus per perfect (+1 Classic, +2 Rush) + 2 for every 5-perfect streak.
- A glowing ring marks your best height for the mode; pass it for a NEW BEST.
- P or Esc pauses. Your run is saved: Continue picks it up exactly where you left off.

About Tower Stack
Tower Stack is a one-button timing game in a soft isometric twilight. A pastel glass slab slides back and forth above your tower, alternating direction every floor. Tap to drop it: whatever hangs past the slab below is sliced off and tumbles away, so your tower narrows with every imprecise drop. Miss the tower completely and the run is over. Line a slab up exactly for a PERFECT drop that snaps into place with a flash; five perfects in a row grow the slab back a little. The slabs speed up as the tower rises, the sky deepens from coral to violet and the city below disappears into the haze. Score is your height plus a bonus for every perfect drop. Classic mode climbs steadily; Rush starts faster with a tighter perfect window, but perfects count double.
