Its an ok platformer. Performance is a big issue. It inhibits the control responsiveness.

This is a good game, and i like how it is really hard, you could make a sequel for more levels or something, but the game is good on itself! ^^

The art is pretty good, and it's a game that mostly works. But that's all it has going for it. I'm just some stupid red block who's supposedly a thief, but why, what am I stealing, for what purpose. My goal is so mundane. I made the same mistake with my first game as well. in fact I made the EXACT same mistake. You need to add reason. Also the block slides over this already ridiculously small place making it impossible to play at times. Not only that but the hazards collisions are huge, as well as they kill you and you just teleport to the start completely lagging the game out. The scenery is nice but why is it like this? This game needs ALOT of work, but I look forward to version two.
This is also a game that really needs music.

Controls are a bit slippery. The levels get difficult too fast. In some ways, this comes off more like an alpha than a beta.

Everything works as it should as far as I can tell. Maybe adding some background music and a stylized font would have improved it a little. As well as some more player animations e.g a death animation. Apart than that it's a nice start to a game.
