It was the web version.
Ok. I think there was an issue with the last functionality I added that reset the power level after a jump. I was on the fence about including it anyway. So I removed it. You can change your power level after the jump but it does not reset after you jump now. It made the game slower.. and I did not really like it anyway. I am doing new executables for Win and Linux with the change. I have already uploaded the new web version.
