pretty nice but a bit glitchy. I got all the shards on level 2, but it said "one shard left" and I couldn't continue. Also, your cat walk cycle programming does need a little work, since quick flips creates a reverse drag

This is actually good, but sound is missing, and it feels a lil' boring. This is a bit TOO HARD, so i took half an hour to get trough it and make the review (i like to complete the game before making reviews) So yep, good work.

The scoreboard could be made a bit nicer, sounds would be nice and maybe make the ice crystals somewhat relevant to the game because a kitty, red & green blobs + ice crystals don't really make any sense other than that the gameplay itself is pretty smooth

The portal is for completed pieces. If you want to get feedback on work in progress games, upload them to the Dumping Grounds and show them off to people on the BBS.

You're off to a promising start! There was one star under a ledge that I was having a hard time getting to and it was becoming cumbersome to keep circling around to attempt for it... So not sure how much more is past the first door, although that fireball in the thumbnail looks cool.

This appears to be made with GameMaker and I'm wondering if it's running as fast as it can in my browser or if it could run smoother. You could try setting the room_speed to 60 and see if that makes a difference in the browser.

Sound effects and music would of course be great, the first three sounds I would plug in would be the jump, the stomp of an enemy and the collection of a star. When you land on an enemy, it would be great to see their face turn sad and give them a quick squashing animation.
