nice presentation and controls, although my biggest problem with the game was the camera. For example there have been times where you drop down and the camera doesn't show the bottom but there were never spikes on the bottom until one time there was and I couldn't tell until I died to them. And then when i realized i had to dash over the spikes i also couldn't see the other end of the fall so i didn't know how far i needed to go and again fell and died. I usually dont like to bring up too many criticisms in a game jam since this is for fun but considering the camera was the one thing keeping this game from being honestly good i thought id let you know so you can improve in the future. (id recommend zooming the camera out for a game like this, and it'd be better if the camera didn't follow the players y position. Unless of course you need it too if the payer needs to go up or down past the camera's view)
Also if you press the jump button twice quickly you jump higher which is the only way to get over a wall which is right before you get the dash upgrade. This isnt a bad mechanic but i at first thought it was a bug since you didnt mention that this was possible in the controls. So i wouldnt be surprised if alot of people stopped playing there.
Anyways, I hope you take this criticism well. And at the end of the day you made an enjoyable enough game in 2 days, good job. :)
