Honestly, just a blast to play through. The sound and visual effects are perfect and when you get the combinations going, the ensuing explosions have that sweet crunchyness, that impact that it needs to be really satisfying. I'm not entirely sure if it's intentional, but at one point, everytime I'd level up, two of the upgrades would be Special related, which didn't really fit with me since I didn't use the Specials a whole lot (I probably should've lmao).
With all of that being said, this game is very satisfying to play and also quite well optimised. It only really started to get some small lag in the last 5 minutes or so of my run, and only when I'd stack a bunch of enemies after me.
Nice job on this game! I had a lot of fun playing it!
