Hey,
I love how the game looks - although I instantly removed the post-processing effect but I do that in any game that uses it. Your game is an interesting combination of game mechanics that I haven't seen before. Good job!
Played quite some time and had some runs. It is fun to try to improve on score and get a better highscore than before. There were two things I didn't like though (nothing too bad, but still):
1. The "read this before playing" wasn't shown correctly on my 3440x1440 screen. The background was shown just fine but the textboxes where placed weirdly and I couldn't read everything. Besides I think you have to read TOO much before you could start the game. I'd rather directy hop in and play some kind of super tiny tutorial level instead of reading 4-5 different options in an explanation menu.
2. The "wall of death" does a sound when it eats up blocks. I think this sound should only be hearable when the wall is on screen or at least VERY close. I could hear it the whole time and that was a little annoying.
Wish you all the best with your game!
