Hey, this is ntwiles from the discord.
Ok now this is a great idea. Very intuitive gameplay. You did a great job of ramping difficulty and teaching concepts naturally through gameplay. I beat every stage and had a great time playing. Seconded on the comments about the vacuum sound for the tube effect. So satisfying.
I will say that some assistance in getting pieces into the tube would be nice, since I found myself getting stuck on corners a few times.
All in all amazing game. I hope you continue development on this and make a full release out of this!
