Nice game. Made it to the end. Appreciated the iframes at the start of rounds. Felt a little easy since hearts reset on level, but it didn't stop me from having fun.
One of the frogs (the green ones are frogs, right? They seemed like frogs the way they hopped... and they're green). Anyhow, one of the frogs jumped kinda low and seemed either really hard to (or impossible) to dodge. Not sure if that was intended or not?
Good job on this!
