I just released my first game for sale, a retro inspired 2D platformer built with Construct2.

I've also put together a free demo, with 4 SMB inspired levels. It's short, but gives you a good idea of how the full game plays. The game and demo are available on both itch.io and Game Jolt, and can both be downloaded directly from my website. Thanks for viewing!
