About your build, It's a start but It's well difficult, maybe you can make it similar to galaga,galaxian or space invaders just to be safe or you could give me a cheat,Also how will I start the character PV that looks like a dating sim?
By the way ,I hope you make a roguelite game based on my game suggestion at the same time that involves a sexy naked woman battling monsters with no clothing and remain naked ,especially when its plot is based on two of my plot suggestions like
1) A female space explorer who landed and explore a planet full of tentacle aliens and female naked aliens when suddenly the female naked aliens capture her,rip her clothes ,gets her naked and lands her in jail where she will soon be bred/rape to some tentacle species to give birth to their species both tentacle species or female naked alien,now the female space explorer will have to escape from the planet by fighting against the aliens naked without any clothing and reach her spaceship before the aliens defeat her and capture her to become their breeding slave permanently
2) A dimensional one about three girls who are on a tour to some ancient ruins when suddenly they are suddenly dragged by a strange dimensional gate which also rips their clothes off and landed them in a weird dimension naked there they are caught by tentacle aliens and made the 2 girls into mindless naked breeding slaves to give birth to their species,Now the 3rd one who is lucky to escape will try to fight against the tentacle aliens ,rescue her friends ,return them to their senses and go back to their dimension.The game ending will have the third girl along with her friends who are normal again beat the final boss freed the female naked slaves ,return them to normal and then have the three girls return to their home world while the freed female naked slaves will rebuild their civilization and use the now extinct tentacle alien parts to give birth to the females, but the twist is that when the three girls return to their dimension they realize they are still naked without any clothing in shock
