Pretty hard to play, not much motivation to continue, works well except the jumps are very hard to control. I missed a platform waaay too many times for this to get a high "fun" rating.

Good fun but found it rather hard, this is certainly a precise platformer. I always got so close but not quite. Some of the backgrounds made my eyes go funky.

Also for other players, 'e' opens the doors

Here are a few pointers that might help you on your next game:

Think carefully about how you lay out the control scheme. It's generally a bad idea to make people remove their hand/finger from their movement keys in order to attack. Also, if attacks are so weak and combat so difficult that you must warn the player that it is an option of total last resort, it's probably best to remove the ability to attack at all.

Likewise, jump as space bar works well when the *arrow* keys are the movement keys, but not so much when "a" and "d" are.

I'm afraid the gradient colors in the background of the 2nd room were so harsh that I literally couldn't look at the background without experiencing actual physical pain. When combined with the incredibly unforgiving inertia and the awkward control layout on the keyboard I simply could not continue once I passed that doorway.

The controls are rather sensitive. They could use a bit more tuning. Some kind of exposition might also be helpful explaining what this special magical macguffin is and why I want to get it.
