The game's very hard for me...

Yes, the game is challenging. But do persevere. Each level is designed to require you reason a little about what keys you'll need, and how fast you need to approach obstacles. If you really have to, do skip levels - you may find some of the later levels easier. And the game does have an ______END.

Cool idea! I liked the difficulty level. Graphics were so-so and it could really have used some audio.

Nice idea, but I agree that it gets too hard too fast. Then again, plenty of gamers thrive on frustration - I'm just not one of them :-)

Good game :D nice concept and good puzzles :D
I agree, could be difficult soon, but player don't have so much possibilities, you can always try it all :D

My favorite game played so far! I like the challenge, and the idea you can skip the level if you get too frustrated. PERFECT! I like that you can pick what directions you want to use on the level, it is a very nice design. Challenges you to think and to perform. Love it mate, you got this one done very well. Next time add some audio! ;)

Interesting idea.. but it can be very slow at times, and frustrating when you can't recover from slight errors.

Phew, it's tought. The first stage with three keys did me in. The curve on the right is killing me.
The idea itself is great though! More stages, easier difficulty and you have a winner.

The control scheme is so floaty that when I die it doesn't feel like it's my fault: it feels like the game is just annoying.

Obviously these controls are intentional and central to the level design, but this makes it not fun for me: it's not quite the same (good) kind of frustration that some games pull off really well.

I think perhaps there's a problem of visual representation. When I try to polish this game up for release elsewhere, I'll look into making it clearer what the directional keys really mean - they are a slow nudge, like a rocket on a heavy thing trying to speed it up or slow it down.

(Clearly this game represents my feeling that we've all been spoiled by having sharp, responsive controls and should return to battling with the inertia in Lunar Lander. :P)

*bounce* -> "ooh, I discovered reverse!"; very nice integration of theme, gameplay and story altogether. I wish it was more challenging though - not in a way where you need insane precision, but in a cerebral way.. perhaps if the X discovered Braid-style time travel... :-)

Oh my, this was very frustrating but very cool and original idea.

This is really neat. :)

A bit frustrating, but very original.

I like the idea, and I agree with previous posters for difficulty. I really intend to explore all the game ( I was wondering how many key you will use ) But I failed on the level where you have to use [R]everse. Dont know If it was a brain or skill problem...

Too hard for me as well. Played it a fair bit though, it's a pretty good game if you have the patience for it.

It's really hard!

Wow,that game rocked! And I found it not too hard! It was hard enough to be challenging! Very very good job! I liked the C-C-C-C-C-C-Detonation ;D

What a shame. The game ran out of levels.

This was very very cool.

I like the idea, but it's pretty tough. I don't like having to choose two keys, it would be better if that was handled in the level design. Controls need a lot of tuning, especially since the gameplay is so focused on the controls. Nice work, overall.

Nice! Some of the levels were pretty hard. Clever idea, and loved the ending.

Interesting idea, well-executed. I got as far as the Reverse level so I don't know how much more there is, but especially considering the time frame, there's a lot there.

The hint system is a nice touch.
