Nice game! I knew music and SFX are 10/10 when I opened the tutorial. I wasn't wrong. :D
its a little hard though. That oxygen cylinder doesn't really run out because you are hit by an asteroid when trying to regenerate shields. you could slow down the time during hit.
art is also very cute. loved it. after a little balancing, its going to be a super fun game!
And if you wanna try my game, it also has a web build in its description. ^^ good work!
