Very interesting take on the theme, I liked it. The tank controls for movement were a bit odd and floaty, but nothing too uncomfortable. The low poly environment was nice, great use of free assets! Also the music tracks in stages two and three were perfect for the situation. I would have liked a checkpoint in stage three, it was annoying to have to start the stage all over. I did make it to the ending though! It was cool that you fit a bit of a story into a jam game.
There were a few friction points that made the experience a bit more frustrating than I would like. In the second stage, sometimes the gravity would switch right before I grabbed a fragment, so I would miss it. And I didn't want to cut it too close to the end to make it easier to grab, because the bottom of the screen kills you from much further away than I would expect. Thankfully though, if I missed a fragment I could just keep trying when it came around again, so it wasn't that bad.
In the third stage, there was a point about halfway through where spiders came and killed me twice while I was trying to read the dialogue before I noticed what was happening. It would be nice for the dialogue to pause the game maybe, or if the spiders stood out more against the dark background it would be easier to notice them moving.
Also I didn't realize for a while that the rotation controls were based on the colored axis lines. It would be nice if the lines were a bit brighter or thicker so it was easier to see the color. However, for my experience it would be more intuitive if the controls were based on the character's rotation, rather than an external object's rotation.
The floating background objects in the third stage were awesome though, good job on the environment. I especially liked the vfx for the portal thing that takes you between stages. That was made in Unity VFX graph? It was hard to make out exactly what each particle looked like (for the purposes of trying to make something similar :) ), but the overall effect was very cool with the colors and all!
I do want to make it clear at the end here that I enjoyed my time in this game, great job!
