Super cool game! I did experience a little bug though, I think.
When I fell down in the beginning, I respawned straight to the end of the level, instead of respawning in the start again. Otherwise I really loved it!!
Yeah I know > _ < I didn't test the final build in the final rush and forgot to assign the initial "lastCheckpointReached" to the first one. I assigned it to the last one to quickly test the last part killing myself right at the beginning hahaha. Thank you for playing it!
