My feedback for CANVARROT:
What the game does well:
A nice attention to detail is the layout of the levels in the paintings; they're mirrors of the real world because the bunny painted it from their point-of-view.
The UI assists for teaching the player controls are easily-readable.
Character's jumping feels balanced.
The puzzles are well-crafted. I didn't feel rushed and could take my time figuring out the solution
What the game doesn't do well:
The first level tries to teach everything to the player at once. They have to learn how to move L/R, jump, pick up items, enter paintings, and take items with them into a painting and back all in just the first level.
It took me a few minutes to realize I could take a box with me into the painting.
Minor thing: the soundtrack doesn't loop
Areas of Opportunity:
The game has a lot of potential to be a puzzle platformer that can teach the player everything it has to offer without overwhelming them.
I recommend to take level 1 and divide it into 2-3 separate levels where you teach the player one thing at a time. As your players progress begin to combine things like you did with taking items in/out of a painting with you.
I hope this feedback helps!
