I've tried Bloxors before and I remember not being able to beat level 3 or 4. Neat game but huge learning curve.
If you've never played them before I highly recommend
Mateusz's games.
The entire Submachine series, Covert Front 1 & 2, and Daymare Town 1 & 2 games are his most famous.
Eyezmaze is On's site. The left side of the screen lists all his games. Pay particular attention to the Grow games, and to the masterpiece "Dwarf Complete" tucked all the way down there near the bottom left. That one is HUGE.
Nifflas has 3 downloadable games (all squeaky clean) that are incredible. Within A Deep Forest, and Knytt are excellent. Knytt Stories is okay but not as good as the other two.
The Cageling was made around 2002? Click the Play Online link near the top. This is beautifully done.
The
Hapland series will tear your hair out, in a fun way.

this silly game just cracks me up. More of a web toy than a game.
