I usually don't feel the need to comment as much as I used to, but seeing that the commenter below me does not understand how the game works, I feel it is my duty to point it out.
You are a cube that cubes moving until you hit something. That is how it is supposed to work and that's what adds the difficulty.
As for what I think of the game, I do like it and I won't fault it much for the simpleness of the graphics (especially since it is your first on here and it seems like you were trying to create a fun challenging game and not a visual masterpiece). It certainly is challenging, but I found some problems with it:
- It seems like the level design could have been done better. There are too many loopholes that you can take to get around challenges, especially early on. It's both good and bad because a lot of puzzle games will only give you one option, but I have the feeling that this wasn't what you had in mind.
- If you fall off a ledge without jumping, you can still jump while in the air. I don't if you intended for that to be the case.
- I don't know why, but playing the game forces my computer to work pretty hard, which doesn't seem to make sense. I've played tons of games with a lot more going on both in visuals and in action. What's going on in the game that's causing this?
- Although it is a minor detail, try to make things like counters and level select screens more diverse and not just with plain text: this creates a type of disconnect where it makes it seem like I'm interacting with an application when I should be immersed in the game (also, it just comes off as laziness to some people, no offense).
Still, I had fun playing it and that's good. I look forward to your next game.
