Hey! I remember playing Extinction Denied last year! :)
Just the right amount of chaotic "Hope you enjoy losing" to "Deus Ex Cellina!" power creep for the rogue-lite upgrade system. At first I couldn't even make it to the first boss and was struggling just to click the little guys, then after a few rounds the game was just "Hey you have all the upgrades! Enjoy endless mode!"
Being able to change the game speed was really nice to just speed through the first few waves, and absolutely critical for later levels where even half speed I was struggling to keep up (endless mode).
Really enjoyed the visuals and the music selection. That "pop" was pretty satisfying when eliminating the enemy cells.
2 (possible) bugs:
- After defeating a boss, it doesn't pause the game so the health regenerates in the background. Maybe refilling the player's health to max after a boss would be nice though.
- After getting all upgrades, it infinitely seems to upgrade the health (or at least it keeps giving the same message). Not sure if this is intentional or not.
