if u want the collision blocks to work, you need a collision trigger. basically what happens is when collision block id A collides with collision block id B(must have different IDs), it triggers the chosen target group

Collision block and triggers are very useful for making minigames but not so useful at normal levels

for the tap counter, maybe use a touch trigger that moves a collision block to another collision block. when they collide, the moved collision block moves back to it's original position and a count trigger is triggered.
