### 1/5 — So Unstable

*2025-08-26*

The game crashes every time I beat a level. That would be manageable if it’d at least let me progress to the next level before crashing. I have been stuck on level 1 because of this. You need to fix this, I can’t play otherwise.

### 3/5 — 3 stars

*2025-06-21, version 0.9.5*

Lag on level 7 fix that the it’s 4 star add landscape mod 5 star

*2025-01-22, version 0.9.5*

You will need:
A PC
A Steam account
£17 pounds (value is in UK pounds and may change due to sales or inflation)
Step 1: Open Steam
Step 2: On the store page, search up “Portal”
Step 3: When you see an item named “Portal Bundle” including 2 games, click “Add to Cart”
Step 4: Open your cart
