Good stuff
Mechanics feel good, kinda puzzle gameplay.
How many coins are there supposed to be by the way? Couldn't find a way to get one but pretty sure i still have 18 of them. DId the game say 30/18 meaning there are 30 coins total? I must be blind then. Nevermind, the coins are just not detected correctly, It adds the coins everytime to rebeat the level. I have 19 coins. Is that all of them?
Here is some criticism aswell:
There are many ways to get soft locked (force restart), especially using glider where you are not supposed to be.
If you have glider energy when you die you can use glider on respawn (for a very short irrelevant amount of time before the game detects you hit the ground).
It is kinda difficult to land on a specific block/pixel because of inertia. In some places you cannot see the gameplay and are given little to no time to react.
Amazing entry for the time given. Good job!
