Wow that's a really impressive time. I haven't been able to get under two minutes so far.
Thanks for the detailed feedback. I'm planning to do a little update after the voting has ended which will address some of the points you mentioned. I want to make a few (wall) jumps a bit easier and being able to restart the game (from the finish screen) is a good idea to keep up the flow.
I don't know whats up with the player character after respawning. The spikes and holes are triggers most of the time. On enterI set the position of the player to the start position. GBStudio seems to keep the momentum of the player anyway. At the moment I have no idea how to fix this. Maybe I will have to modify the engine.
Initially I did not plan to continue to work on this after the jam but designing these small one screen levels was really fun. So maybe I will add an extra level. I still have some ideas for new game mechanics, like moving or disappearing platforms but am not quite sure if I will be able to realise them in GBStudio.
