Awesome game! Was playing non-stop for 3 hours :D
Feedback
1. Tornado - very awkward hitbox, also 2 unlucky tornados could trap you, especially then you become big. Don't mix them with sharks or limit to 1 on screen or something
2. Unpredictable shark sizes. In first I assumed once I ate one, I will eat them all, but next shark was bigger. Not a fan, but ok. In other runs I was able to outpaced their size, and saw smaller one after bigger one, a bit strange. Personally, I think shark size can be locked, but with different enemies after bigger sizes
Bugs & QoL
1. Easy to miss bonus if other edible unit nearby, because of "chew cooldown"
2. Golden fish could use more distinct graphics. At least bigger glow?
3. Sharks spawning while bonus on screen at bigger sizes
4. Shark can instakill you, if you are on the edge of the screen
5. Left - Right movement feels janky. Sometime one jump will bring you to the left edge, sometime tornado pushes you to right edge. Maybe even lock horizontal axis.
If you want to improve gameplay and feel, I can also recommend to look how similar games do this stuff. For example jetpack joyride.
Love you work!
