This reminds me of Thomas Was Alone. I liked the concept and the art. I just think the difficulty curve is too steep. You should try to introduce the mechanics more gradually in your next game. Cool game in general. Well done!
Thank you very much. I will work more on UX in my future games because most people pointed out this fact. I never in-game indicated that shift makes you jump faster and jump higher...( Also I'll work on movement mechanics as they feel... unpredictable and junky.)
