Very cool entry!
I think the gameplay works very well, at first I was afraid of touching any tiles because some games kill you if you do that. It was nice that it didn't, because that allowed me to go much faster. I think the floatiness of the character is appropriate, and I felt like I was in control the whole time, which is good! Maybe you could add some more content if you continue working on this, it could eventually be a good mobile release.
I think the theme works well in terms of the setting, but I think you could use some more mechanical tie in to your gameplay. Maybe if you hold the jetpack for too long you get overheated and become faster but can't stop boosting, you can only change direction or something. It could be a good tool for speedrunning and a great way of adding a bit more depth to the game, imo!
The aesthetics work well enough, although my only suggestion would be to remove the outlines from the base tiles. I feel like the rest of the game has a line-less look, almost like silhouettes, so the tiles kind of break this aesthetic.
In terms of sound, I think the music choice is very good. However, I think the jet pack sound effect could be done a bit better. Right now I think you just play a sound whenever the player starts boosting, but some of the sounds are a bit too long, so the player hears the sounds cut off if they spam click to control their direction a bit better. My suggestion would be to make the start boosting sounds a bit longer, and add a short "tail" sound whenever they stop boosting. You could also add a loop of the jetpack to the mix, so that the player has some sort of auditive feedback as long as they're holding down the mouse button.
Cool entry, keep up the good work!
