Wasn't expecting much when I clicked on this, to be honest, but glad I did. While the idea isn't all that original, yeah, doesn't stop this game from being pretty fun. Square pillars of water did seem a little silly, but given its purpose, we can allow for some wonky things here and there. I think it adds charm, personally.
Haven't listened to audio, but I usually don't judge on that department unless necessary, which it isn't here. Headphones ain't working anyway. Most games trying to follow this formula is just sticks, quite literally (at least in my experience), so good on you for actually drawing art. Shapes usually aren't my thing, but the game works well, as does the physics (imagine the look on my face when they actually were present!). Adding in fixed shapes as well as dynamic ones is a thing that separates it from a good deal of stuff that I've seen.
I don't really have much more to say, but this gets a 5/5 from me. It's actually pleasing to the eye and the idea was done pretty well. Someone tries to tell you otherwise, I think they're just stuck on bigger games out there that have you pay to play. The standards there don't apply here. :3
