Summary

Though I have never seen this concept before, I have to say that this feels more like a test rather than a game. Add some objectives, levels, awards and such. But again, seemed like an interresting way to open the door.

Suggestions

I wish there was a restart button.
It's challenging though, and fun & addictive.
Way to go!

good

good twit on keepy upy i got 90 something yay

hey man dont listen to these fucks

I,m almost willing to put money on the fact that they have never made anything using flash ever because they dont appreciate how incredibly hard and time consuming it is! GOOD FUCKING GAME!

YAY for potential!

Cool idea! So much potential you have here is amazing!
But as other reviewers have said yer missing something and that thing is GAMEPLAY VALUE. Basically all the game play hangs on one thing - keeping the block in the air. Once you got the hang of that - no more - you're going to stop playing as you could keeping on doing this forever - but there would be no VALUE to it. But do not be bummed out!
For the idea is great and the general mechanics could be left exactly the same.
But insert GAME PLAY value - make it hard and worthwhile for us players to keep that block in the air, by making it harder to do so.
Adding monsters which disturb you, or perhaps cannons which are shooting at you... if you want an example of a good mouse avoiding game search for "Streamline" on newgrounds, it might just give you a few ideas on how to use your game engine in a similar way... at that point you could already add powerups or somesuch thing.
Basically, the engine is great - but making a full fledged game out of it is up to you and your own creativity!
Good luck, and I hope to see a great game come of this yet!
