I left a comment here last night, but it seems to have not sent(?)
Was just saying that I'm impressed at how much gameplay you managed to fit into 'Press Space.' The ice blocks were pretty inventive, and I felt clever when I realised they could be used to my advantage. (I should probably feel stupid for not realising it in the first place...)
I was confused when I failed on the ice level a few times, because the white timer is completely invisible on the white background. I did think it was a bit that failing on the fire level brought you back to the very start of the game, but I did get a case of 'I'll just try one more time...', haha.
Also, exploding was an appropriate way for the character to die, so well done!
