Fantastic concept! As a pinball fan, I was excited to find this, and the game was quite fun to play. :]
I feel like there's so much potential to expand upon it though, and I'd love to see an fuller paid version eventually! If I may indulge in ideas for what could be added:
-I think it'd be cool if there were more distinct table goals (alongside a much bigger/much more complex table). Lots of ruleset examples you could pull from real pinball tables, but adding stuff like ramps, raised sections, drop gates, etc. would make the game more engaging.
-Small thing, but maybe each table goal plays with Aethra in a distinct way, like adding toys or making them lactate, and players can do them in any order?
-Another small thing- I'd like it if the connections between Aethra and the pinball machine were more clear, as now the only connective tissue I noticed was... tentacles on the board. Just about anything would work, but for an extremely detailed example: maybe Aethra IS the pinball table, with the bumpers being their breasts, and shorter table nudges done by spanking them (like how the flippers are here)?
-Wild idea, but I think it'd be fun if Aethra's corruption affected the table a bit more. Maybe they eventually orgasm, causing parts of the table to temporarily flood?
-Most importantly- more polish would be appreciated, especially to the game feel! Pinball FX3's arcade mode has really fast, fun physics, and the table sound effects are suuuper satisfying. It feels really good to play, and I would appreciate if at least some of that polish could carry over!
Regardless of if a second game gets made at all- again, great work on this one. I hope you all are having a good day! :]
(Edit- oh, and out of curiosity- what the heck are the orange collectables? They look like tater tots lol)
