This game looks like a copy of 'Papi Wall', a free game for mac. The collision detection does not seem totally correct and there is not really a special reason to keep playing at the moment. Expand your game, make different game modes, improve the graphics, try to implement some ingame-achievements or so, it will make your game much more interesting!
When you can improve the graphics, the ending and make it less like you're playing some kinda portal-game(although its different, it just looks like the portal game), this could be a good game. For now it does not bring a real gaming experience. Just keep learning and your next game will be better. Good luck!
I think there should be a 'pause' button at the 'free play. It would also be fun to be able to create a 'moving' level (like freeplay but then 'rebuild the animation'). I also think there should be an option 'overlay current configuration to the left', so you can see where your image differs from the level.
You can try to restart by going back to the first frame of your game. I think its a good idea to add a menu, a sort of 'levels completed' counter or something like that. Also, make more clear that you can pause your game by using 'p'.
Try to be more creative, give your game more gameplay/levels before uploading it. Think of a game you'd like to create, start with a simple version of that you can easily extend with more features. Don't try to do all this just on one day, you can put a lot of time in it.
For now, this game is just too easy and too short to be fun to play, but its a good start for a larger game with some elements of the current one.
I think you should improve your graphics a bit (for example your sponge bob(try to make him walk) and your game-over screen), improve the collision-checks (the borders are now not included in the collision-check, though it's better to add that to your collision-check), add a 'replay' button (just go back to frame 1) and your game already seems more professional. For a first game, its pretty good, but use the tips as help for creating better games.
