I really like how it feels like everything was made in Paint.exe — so funny!
I also love the aspect where, if you paint too much, it overflows with paint — really clever idea! The sound effects that go with it are hilarious, by the way.
I also think it’s a really fun addition that you can export what you’ve painted as a PNG!
The only issue I had is that when it overflowed, the whole game started lagging quite a bit. But it didn’t really break the experience or anything. Nicely made! The only feedback I really have is maybe to add some music? But other than that — great job.
