Sorry it took so long for me to get back and check this out, the holidays have been busy. haha.
This was a neat little game! I can't say I'm a huge fan of the timer resetting after only 2 attempts since there is already enough pressure to avoid the spikes anyway, so maybe you could extend the amount of 'lives' you get to be closer to like 5?
I would also opt for more player movement and control, since its a bit difficult to navigate only moving vertical or horizontal but sometimes being able to do both? More player control is usually always the best call IMO. haha.
I also think you could probably add a bit of buffer time between when you die and when you spawn again, since I ended up wasting some of my timer since I was already "jumping" and had to wait for the robot to move back down before I could plan my attempt again.
The art was simple but the palette was nice on the eyes and consistent!
Overall though, while there is room for improvement, it is a neat puzzle platformer concept! Keep up the great work!! :D
