In its current state, the game feels like a tutorial, teaching you to use the abilities you acquire, but running out of time before challenging you to use them correctly.
The movement in its current state is solid but it might lack diversity to make engaging platforming: things such as a double jump, a wall jump, interactive elements in the world or other such things (not necessarily all of them).
The fighting abilities in their current state are probably too slow and unwieldy for the faster enemies near the end and with how simple the the enemies are, the fighting isn't particularly interesting. As a result, if you had had time to extend the game a bit without having time to add more complicated enemies or to change how fighting works, you would have been better off just removing combat abilities and having the enemies just be moving obstacles.
