I think this is a really cute game, but I have mixed feelings about it. On the one hand, the animations, the pixel art and the sprite work was just gorgeous, especially the licking the space bar. Yes, that is in the game and it makes sense. The wobble effect on the spaceship when we bounce off of something, the bomb and its effect, the sun, all are done masterfully. The style and the color palette all had really good cohesion. However it may just be the shortcoming of my imagination, but I just had no idea what happened in the intro cutscene. It felt like a fever dream to me. An interesting fever dream with a well defined color palette, but nonetheless it just didn't convey what happened, which is a shame. Still, the art was this game's strong suite.
I really liked the gameplay, it was simple but it had a nice idea, the small levels fit really well with the limited pixels. At first I disliked how slow the acceleration is and how bouncing takes away all momentum, it felt clunky. After the first level though, I began appreciating its higher skill expression. I'm not sure how much thought was given to the level design and where we're intended to use the bomb, but it was really fun to just blow up one obstacle I did not like and just slip into the portal eye thingy in time.
This is something you addressed, but the addition of more sfx and music would've elevated the experience much more. That is the only thing though that I feel lacked polish, but other than that I found this game to be really well made and polished. Also I really liked the different death messages. They got slight chuckles out of me.
(One slight note, I may just didn't go far enough, but you should've definitely hid a secret in the ending room, why else would you let me get out of the map?)
