Thank you for your kind comments, all! Cheers to everyone for making such great games for the Robot Party jam :O)
Leaving this info below for anyone interested:
I used OHRRPGCE (Official Hamster Republic Role Playing Game Custom Engine). The engine is capable of much more than I used it for and its webpage has a lot of resources: https://rpg.hamsterrepublic.com/ohrrpgce/Main_Page
Other than the chewing audio, all sound effects are by Foxley via this library they shared on slime salad: https://www.slimesalad.com/forum/viewgame.php?t=7465
Oh! And Aseprite for the sprites: https://www.aseprite.org/
