Honestly, an incredible demake — the gameplay is perfect, super responsive. I see you even made several levels on top of that. It’s really addictive, there’s nothing to complain about. Truly, it’s very enjoyable.
I don’t see any major flaws — it’s addictive and does its job perfectly. It’s just a shame there’s no music or sound, though. That’s really the only downside. But hey, there’s even a title screen!
