First of all, theme implementation is awesome, fits the one ability theme. Also, the game was fun and enjoyable to play.
Theme is on point and is open in many creative ways to further develop the game from that gravity flipping ability. A theme full of possibilities is a good and solid base in developing a game.
The fun factor was also well done, really entertained me to play for a few minutes. Although this can still slightly improve by adding a few more challenges the further you get.
Onto the weaker side of the game which are its audio and visuals, or in general the presentation of the game.
Audio in the game was fine, but it was lacking. More audio improvements could have been done to show feedback of user interaction or maybe more ambience with the bgm.
Visuals on the other hand, felt left behind.
1. The text could have been somewhat improved with an outline, or maybe different color than white.
2. The health sprites didn't really fit in with its pixel art, possibly taken from an asset pack, (although nothing is wrong with that, it can be improved upon by matching assets with the game's art style.)
3. And also the game effects text, (bigger font, inversed controls, slower gameplay) weren't properly displayed in a neat manner.
Overall, I know how I yapped on the visuals, but I assume this was probably because of lack of time in the gamejam, try to improve on this next jams you join :> But on the brighter side, it really is a fun concept that can be further improved upon with time and dedication. Congrats on submitting a game! <3
