I like visuals, a mix of the game genres. I don't really like the music. I suggest to make first levels less challenging and to replace "RESET" with "PLAY AGAIN" text at the gameover screen.

Fun and addictive game! The game idea is really great with all the upgrades and resource management that you need to keep to get rid of enemies in good moment, everything clicks together and is well designed. And of course the presentation is great - very nice looking, clear pixel art. I think that maybe if upgrades were also of different color it would be more readable - now upgrades are similar to each other ;)

it took a litle time to understand what the goal was and that you had to schoot the  skulls  but  when you know what to do very very  very nice game

Very fun! I admit I was a tad bit confused at first about how to play, but I picked it up quickly and ended up playing for a lot longer than I was expecting. Side note: clearing a level of all the blocks felt very satisfying!

Fun game! Had a good time with it! Reminded me somewhat of Crystal Quest I used to play on my first Mac!

A thing I didn't like as much is that the spawn distance of the skull enemy feels short, especially later in the level when things speed up and they pop up every few seconds. When you're focussed on the rapidly spawning skulls, you can't pay much attention anymore to where you are firing your blades to. 

Furthermore, when you're enthusiastically firing all your blades, and you can't fire any more because you haven't gotten any upgrades yet, you feel like a sitting duck when the skull suddenly spawns. The strategy then would be to always keep one in reserve, but that doesn't feel as satisfying unfortunately.
