If I had to resume this in a word, it would be: Frustrating.

The game starts simple with a simple mechanic, place an object on the ground that pushes you in the oposite direction of that ground, not only upwards but in any direction (if placed on the ceiling, it pushes you down)

From there, the game starts presenting new mechanics and objects, but here comes the problem: Almost all of this objects are consumable, and they only restock if you buy new ones on certain spots, or enemies drop them (at random).

This means, that any map should be possible to traverse without using any of them unless on certain situations where they do provide infinite objects to use.

That creates a situation where you are stuck in the doub of either using the object and risk not having it on later parts of the map, or not using them and ending frustrated with the game.

The developers must have thought that the people would guess when they should or should not use any of the objects, but it's not so easy.

This creates a gameplay that feels frustrating and confuse, where you die without knowing if it's your fault or where you did wrong.
