Ok, let me say the good things first: The game seems pretty polished, with box eyes and Flashlight artwork. The jumping different amounts depending on how much you hold is a great quality of life feature too.
Now for the criticism:
The Boxes are really frustrating to climb, i keep bumping into them and smashing my head on them, making it pretty hard to navigate.
Despite the flashlight, the boxes are still really hard to see. Would be nice if the flashlight had a bigger viewcone, or the boxes were visible for longer, or if the eye patterns were explained, or all of the above.
The level looping is really strange, it would have made more sense if it was on a timer or something and you were constantly trying to beat your best time or something, but you aren't. Maybe a few more levels or a least a win screen where you could restart would be cool.
A background could have helped a lot, or maybe even a few effects.
Conclusion: Amazing and really fun. The level of polish and prototyping is very high, especially for 48 hours. Could have had a bit more work in a few areas, and is really short. Overall i'm rating this game 3/5.
