Haha I'm glad you enjoyed it, and especially glad you noticed all of our worm-flavoured set dressing ;) The background music was from https://incompetech.com/music/royalty-free/, but every single sound effect and voice line otherwise was hand-made by us - including the very authentic apple eating sound effect that took me two apples to get sounding right haha.
Yeah the lack of levels was our biggest regret, we just ran out of time in the GameJam and spent most of the 72 hours on the aesthetics and game mechanics. We might polish it up a bit and release a post-jam version in the future with more levels and better balancing!
And even though the textures were not inspired by Megaman Legends as I'm afraid I never played it, I'll definitely say they were if it makes us sound better! ;)
Cheers for checking it out, it was fun to watch the stream!
