I love the graphics in the game! You did an amazing job! The music fits well with the aesthetics as well. The gameplay is simple but has a lot of potential. I'm interested to see what else you can come up with for level designs using the telekinesis mechanic + levitation.
The enemies have too much HP. I think you should make them die in 1 full charge of your hand laser. It's the first level after all. I'm not sure if this is intentional but if I jump on a cube, it damages me. I think you should remove collision from the enemy parts after they die. It makes it difficult trying to move past areas where there's a bunch of enemies. You should use the food as an item. For example: levitate the food towards the alien and they get distracted by eating it or something as simple as healing you.
Also, I failed the tutorial :)
When I tried placing the blocks, it immediately jumped to the left. I think it might be the collision interfering with it. Maybe you should space it out a little more to prevent this.
Overall, great game! I had fun with it.
