This was a spinoff of my SpartanTech font, based out of the Halo 3 Video Game. I would describe it as representationally techno-militaristic.

Pixel-based font based on Acclaim's Extreme-G on the Nintendo 64.  Plenty of custom characters included.  Enjoy!

There you go! I made a usual recreation of the dialogue font used in Kirby’s Avalanche (a.k.a. Kirby’s Ghost Trap in Europe), Nintendo’s attempt at localizing Puyo Puyo in the 90’s, before the time when SEGA bought the Puyo Puyo license. Almost all glyphs from the game are included, as well as custom glyphs for other languages. Have fun! Bayoen~!

This is SquaredEyes57. A pixel-art font I made to use in the games I make. Every Character is within the bounds of 5x7 pixels. This is the second iteration of SquareEyes35, which was only 3x5 pixels and turned out to be way too hard to read for longer texts. I hope it can be useful for whatever you need. 

A remake of the font from the GBC production "Mental Respirator" from the Phantasy demo group. (A few of the characters I interpolated for the full Basic Latin Charset)

All design credits for the original characters go to Exocet of Phantasy
