Great game, very fun! The HUD is impeccable, very nice presentation, nice use of colors and sound effects. Also, I died a lot, still trying to figure out a flow to reach higher!
Suggestion: sometimes (a lot of times) I ended up being trhown to the lateral, going to certain death. It would be nice to have some mechanism (maybe an item?) that would allow the players to redeem their misplays, throwing them back to the middle of the screen. I don't know if it would defeat the general purpose of the design. Anyway, brilliant game, good job!
