Oh boy, this was hard.
What I liked:
- The tileset is great. "levels" feel organic and interesting.
- I love how everything pulsates but still stays pixel-perfect.
- The bloaty spikey obstacles were very well implemented.
Suggestions/advice/bugs:
- The game was too hard for several reasons: Controls were not precise enough for how the levels were designed. I'd often find myself in a situation where I had no way of avoiding obstacles.
- The knockback was too strong. It often knocks the player back to another tentacle, and another.. resulting in going back more than the current checkpoint's worth.
- If I got hit multiple times (by the rotating ones especially) my player would get stuck and unable to move. The only way out was to reset back to the checkpoint.
- The "sine wave" of the player moving is a bit too obvious. It gets distracting and takes away from the good visual experience.
You made a great rage game. Not sure if you wanted to though. :)
