Okay so here we go!
positive:
°I love that you just rolled with the prefabs. It really has its own touch. It kinda feels innocent and wholesome. I like that. It works really well
°The movement is really tight and I like that fact that you stick to the wall, when doing a wall jump. Makes an old mechanic looks fresh again
°you respawn just at the right place
°tbh it looks cute when the block crouches
°the cube textboxes make them very alive, very cute
°fading into the other level looks smooth and feels nice
°when entering the levels with the environmental cubes, it's fantastic! You set them to look really amazing, eventhough there just some gray cubes, really mastered that
°Sound is good!
negative:
°When you want a rolling text, make sure to place it at the left, if it's centered it's really hard to read while it rolls. Maybe use a fade next time or sth.
°The camera is placed too far to the right. When moving left--> right, you wanna see more of the right!
°The tutorial(first level) is a bit too long distance wise. Most of the time you only move forward. You can shorten that a lot, without having any negative aspects
°The UI is kinda hard to read, maybe place it a bit lower and change the color to a darker one
Issues I found:
°I found a bug at the second wall jump obstacle. All movement got blocked, when I hit the second walljump block. I restarted the game about 5 times. Maybe have a look at it later on
°First bridge collider is a tiny bit to high
°Boss level, the particle effects got overloaded, didnt dissapear... it was kinda funky xD But I guess not intended
So all in all I enjoyed your game! It made a lot of fun and it just has the right difficulty level!
