This game actually has quite solid mechanics! Snakeout (im really sad you didnt call it that) is a really good combination! and i like the ball upgrade mechanics. Onto the critique, sorry if any of it sounds a little harsh
The initial experience was a little confusing, to say the least. I was disoriented by the moving camera (which isnt present in snake or breakout), and was kinda unsure what each powerup did or whether i should touch them. Some more tutorialisation would be apreciated there i think, though it's simple enough that the game can make do without
Admittedly, i quit after i breached the first line of blocks. Seeing a whole extra line after a long corridoor was really disheartening, as my balls were HUGE and i'd have to just snake around for ages to get through. I think your core mechanics might've worked better in either a one-screen level based game, or in some kind of roguelike where blocks just kept coming and moving down the screen
I found a bug: if you quickly press a turn direction (going up: A or D) and then backwards (going up: S) you can crash into yourself.
The music is kinda rough, i found. Some of the chords sounds really like, out of tune. I dont really know how to do music critique so sorry i cant be much more detailed.
Overall, i think you made some quite solid core mechanics, but fell a bit short in other areas. I still had a decent time though :)
Thank you so much for taking time to write your review!
I think I'll add a tutorial in the menu and rework location after the corridor. Tha balls don't stay huge forever, every time you take a powerup it lasts only 15 seconds, if you don't take another one. I really want to fix crashing into yourself bug but I won't remove this feature since it enables players shrink if they feel too huge. I'm really bad at music and even worse at working with musicians so music will stay horrible :( Thank you again for the review, I really appreciate the citique, because it helps to see what works and what does not. If you liked the game consider trying other my games too, I like to do exerimental stuff
