Rogue Blast was my first released game.
It was made in 48 hours for Ludum Dare 37.
It used the LÖVE framework. I wrote all the code. Created all the assets. And made the music (Which I might have stolen).
This game was my first attempt at procedural generation in the form of generating the levels.
It also features a rich set of "items" to try feel like a rogue-like.
Overall I'd say it's really quite good for a first game
