Thanks for thw update. I was about to complain about the d-pad size too.
Aside from that, its a nice game with good visuals and music.
I loved the secret mode and the idea of "rescue" stage for each zone.
Heres a couple of suggestions/complaints for the gameplay:
Its hard to see enemy respawn points. I think it has some kind of particles but its barely visible. Try maybe adding a blinking enemy on top of the particles?
Enemy movement is jarring, they seem to jitter up and down while moving. Also, maybe try making a better path finder for these?
The enemy collisions are very janky. Sometimes i squash them form very far, other times i can push ablock on top of them and they wont die.
You can lose lifes very fast. Give Dizzy more invincibility frames.
You gain lifes too fast, i finished the game with 17 of them left.
The two points above indicate a lack of balance. Life are now expendable trinkets rather than valuable resource.
Add a extra lifes tally at the end. Give players some extra points for each life.
Small animation glitches here and there(like dizzy changing animation to idle between victory and bonus stages).
