Yay! Unreal game! Not very many of us are there.
Very cool concept I enjoyed the puzzles, which I think is the most important thing. I just wish you would expand the presentation aspect too. Simply using more lights or applying a color pallete to your game instead of using mostly default materials would greatly help without too much effort. That being said it is really a cool concept and I always like to see more UE Jam games :)

Hey this is a neat prototype. I'm quite pleasantly surprised if anything.

Some good things are,

You've done some simple but effective use of puzzle and level design. The tutorial was quite nice to introduce the mechanics and the early levels help illutstrate some level design.

My caveats are that,

I got softlocked in level 2, when removing the yellow wall from the ceiling. I couldn't retrieve the final block to get to level 3. The jankiness detracts the experience a bit but you've definitely got something going!

Fun concept. Got softlocked by grabbing a box from afar and flicking it through a solid wall. Retry button that reloads the scene would help for these scenarios. Now following the project - I'd like to see if there's updates to it.

The concept was pretty interesting, but I found the gameplay a bit tedious. Every room started super stressful, requiring the player to quickly find the box to shoot at the things, then move each of the blocks to their places. I think a little more puzzling and less threatening would be good!

Great work, got a lot of half life grav gun vibes from it. Great concept. Could use some polish to bring it that last little way, it was a bit fiddly to get things to work, and some visual indication of what mode the gun is in/if it is currently active (esp. on the move setting) would be good! Great job!

Very good! I liked the mechanics of the cubes and the idea in general! but I have a few points to mention: The enemies didn't match so much I think only the puzzles would get better, the first puzzle with the enemies is very complicated for the beginning and I had some bugs of the door closing forever and my only box going away (one retry button maybe). Apart from these details I enjoyed!

Pretty good concept, and pretty fun too. One of the first games I've been able to play through till the end. Definitely needs some more design thought put into it. The enemies are more annoying than dangerous, and the puzzle's mostly consist of "Find all the hidden cubes." Great base but with a lot of growth potential. Also cool to see an Unreal game.

Nice concept, really original.

The enemies were more annoying than a problem, IE you either won instantly or lost.

Though I managed to get myself trapped in the room with the three switches...
