Fun and well-polished game.
I noticed that no levels require the player to use the angel’s ability to shoot the imps. When replaying some levels, I forced the use of that mechanic by challenging myself to kill all existing imps during each angel round. I hope the expanded version has levels built around that mechanic.
The level Overwhelmed’s high round count made it exciting at first, but the level turned out to be disappointingly easy. I didn’t need to use most of the platforms – I just stood or jumped in a unique spot for most of the round’s time, then headed to the exit. I wish I had been forced to use more of the available space. In the expanded version, one mechanism for that could be having a tight time limit and scattering Extra Time powerups in the far corners of the level.
