Im not sure if spacebar thing was intentional, but I think it break the game a little, otherwise very pleasing to look at and audio fits really well!
If you mean the spacebar spawning more gems even after getting far into the game, no it's not.
My mistake on that part. I was rushing the game last night, so I got careless. I'll fix that post-jam.
Glad you like the visuals and my choice of third-party audios.
Thanks for playing. :)
