Good game.

Nicely executed ... Really connected to theme.. Although quite disorienting ...I was looking at the box whole time, when actually W was the player :))

This made my brain hurt in a great way. I enjoyed it

Cool idea. Control scheme needs work though. Found just controlling my character to be the hardest part of the game. I would say make direction keys act as expected regardless of gravitational orientation.

My brain got a really bad time at the last level.

nice puzzle designs

Interesting idea and it is fun, but the music and the graphics kind of make the game look and feel slow and a bit boring

Good game. It got me hooked till the end. Only I don't like the controls. I feel I was spending more effort fighting with the controls than actually platforming.

I like the concept!

Simple, clean graphics, good controls, and a nice use of the theme. Good job!

Fun and challenging game. I like the concept but having to switch between normal and reversed control is really difficult !

Really good idea - clever but easy to get to grips with after a few levels.

Firefox doesn't seem to run. Get the title screen, hit space and get the "W" sound, but no graphics change or music. Nothing further happens. Chrome worked of course.

Really, really nicely done. Impressive for 48-hours. Level 5 was particularly challenging for me.

Very smart level design, and a rather cool mechanic that fit the theme. Graphics and sound were okay.

Good job overall!

Cool concept! Remind me the Portal.

My brain hurts after playing this, trying to keep my directions straight. Quite a fun mechanic! The player controls were a bit difficult though. Overall, a fun game. Well done!

The game was fun. That last level... I couldnt stop! Well done.

Notes: The collision is a bit tricky because it seems you are using AABB instead of a tryangle/square. That is my only beef.

Hi there. Nice idea, very confusing to play - defeats your inner platform-player, which is a good thing I think. Nicely done!

Wow, that hurt my brain. Level design is really good and I think you explore your basic mechanic very well. The control is really hard internalize, it is a matter of taste if it should be easier or not I think.

One small criticism about UI design, have the prompts advance with space, since space is already used in-game, and return has no other function :)

Interesting puzzle platformer. Enjoyed playing it!

Really interesting use of the theme, clearly connected worlds. The music was fitting and the gravity changing makes for a nice overall mechanic.

The game mechanic was pretty cool. It took me a few tries for my brain to adjust. The controls were a bit unforgiving (I almost rage quit a couple times on the last leve), and it felt a little glitchy when switching between a couple of the gravity zones. I think it would help if, when changing to a new gravity zone, you make the old one unavailable for a moment.

I loved the world transitions.

When I try to start the game, the game says "w" and starts flickering between the menu and the level as seen above. After that, I'm unable to get anywhere...

@mfagerland - what browser are you using? I've tested with firefox and chrome and never experienced that problem. Perhaps there could be issues with other browsers.

Well executed, but incredibly frustrating to play. I think you could have capitalized more on the graphics by choosing a colour theme for your graphics, and perhaps sticking a paper texture on everything, making it a "thing" that the game features a typed letter as a character.

My poor brain and fingers hate each other now thanks to you. Nice game though ;)
