BatteryMan by Rami
Story:
Once a day, you woke up, and found yourself in a maze with an electronic heart instead of the natural one, then, a robot comes to you and tells you have been put into tests, you have to finish each level to recharge your heart before it runs out of power.
This is my first Ludum Dare Jam game ever, I had some problems managing my time, and here's what I came with.
I hope you enjoy it :)

About LIKO-12
The game has been made using LIKO-12, an opensource fantasy computer made using the LÖVE framework, and actually it's using a modified version that has Audio support, it loads the wav and ogg files in the Audio folder, give them ids, and then in the game I call "Music(id)", "SFX(id)" and "StopAudio()", I will write a devblog soon telling about all the modifications I made while creating this game.

Note: Android build coming soon !

I really wanted to play this further, but occasionally there was a bug that prevented me from lifting up boxes... :<
After the tutorial, the levels get impressively complex, and seem to do a lot with simple mechanics. The difficulty is not for the weak-hearted, but I for one enjoyed what you did here.

Very impressive. At times the game was very unforgiving - there wasn't always too much room for errors. But difficulty wasn't frustrating - my only frustrations arose from moments like when the box was difficult to take with or the physics made it hard to drop into one tile wide shafts. It was fun nonetheless, I would like to play this further!
Having controller support and even remappable controls is always a huge plus.
My biggest gripe would be how hard it was sometimes to get in line for a single tile gap drop / jump up because of the fast character movement. I can't even tell how many times I messed up by overshooting few times and then had to retreat back to a battery before trying again. Also the wall hugginess when dropping down one tile gaps was a bit too aggressive.
Dunno if you ever introduced the wall jumping mechanic. I think I read all the messages but didn't see anything about it and discovered it accidentally in the last "real" level. Dunno if you even need it, seems like you can almost always be carrying a box and do the jumps with it.
Level usage and box carrying could be different buttons. Messed up many times because of not realizing I was carrying a box when going for a level. Then I pick up the box and switch the level at the same time, panic and eventually run out of battery.
Good job! Hope to see something as awesome as this (or even better since you'll have more experience) from you on the next LD...
I liked the battery mechanic best on the levels where you either had to race through a fairly obvious path, or on the later levels where you were generous with the green charging pads to give the player a chance to stop and think partially through. I thought it was iffier in the pure puzzle levels without "safezones", generally I found the effect it had on me is that was too pressured to really feel comfortable observing what the levers did and such. Maybe frantic puzzle solving was the sort of feeling you were going for, but I didn't find the time limit synergized well for my tastes during these levels.
I thought the controls could have been vastly improved with some quick tweaks. In particular I found it possible to finely adjust my position, it seems like even the finest tap of the arrow keys moves your character an entire block.
Nice game, and it's a great effort for your first LD. Hope to see what you make next jam!
The graphics are simple, but they do fit the style so well, and the audio's also another great point! Controls felt really good to play too!
Great job there!
