Completed with a whopping 285 deaths!
Solid game, had a lot of frustration at some points, but still had a lot of fun with the mechanics. Easy to understand, easy to pick up, extremely hard to master.
Some frustrations:
Sometimes bodies block your vision of where your character is, leading to some frustrating deaths.
Would be nice for a split second of invincibility on respawn, sometimes I felt frustrated when I respawned died again, since that death was out of my control.
Would appreciate an assist mode for people (like me) who need a little more help with games like these! Maybe more checkpoints enabled in the middle of the game.
Some clearer direction towards the end of the last room/level. It felt like I could go to certain "targets" in the corner of the room, but I kept dying and was supposed to go to a different "target."
Regardless, it's a great game, and even for using primitive shapes like you said, it still looks more aesthetically pleasing (at least more than mine :). High ratings.
