Thank you for the review and feedback.
The main purpose of the charging mechanic is to check if player is on solid ground, is not moving, and for previewing the next level (without additional controls).
The delay of lava tiles is the same as the hollow tiles. The idea was to have these 2 tiles with same delay and the platform tile with double the delay.
We will definitely try to improve the explanation of this maybe with an additional sticky note after the jam along with escaping also using P key.
Congrats on getting almost to the end. Levels 36-32 are the most complicated ones, after which there are only the outro levels.
